Jobs Search reference - Crustdata Docs

Reference material for Search Jobs: filter grammar and operators, common indexed fields, the full Job catalog, id semantics, aggregation bucket metadata, null behavior, and errors. For worked examples, see Examples. For sorting, pagination, field selection, and aggregations, see Pagination & sorting.

Jobs ID cheat sheet. The Jobs APIs use three id concepts — keep them straight:

crustdata_job_id — the Crustdata job identifier. Returned on every Job. Use it as your dedupe key.
company.basic_info.crustdata_company_id — the Crustdata company identifier returned on every Job.
company.basic_info.company_id (filter alias) — the dot-path used in filters and aggregations.column for indexed Search Jobs. It points to the same integer as company.basic_info.crustdata_company_id. This alias is not sortable; for deterministic pagination, sort on metadata.date_added instead.

When you group_by on company.basic_info.company_id, each bucket also returns metadata.company_name, metadata.company_website_domain, and metadata.linkedin_id for labeling.

Filter grammar

Every filter describes which individual job rows to keep. The API checks each job listing against your filter independently — it never groups or combines rows before filtering. There are two building blocks:

Building block	What it does
`SearchCondition` (leaf)	Tests one field on one job row — e.g. `title = "Software Engineer"`.
`SearchConditionGroup` (node)	Combines conditions with `and` or `or`. Groups can nest inside other groups.

Exact-match AND on the same field always returns zero results. One listing has one title, so (title = "Software Engineer") AND (title = "Account Executive") can never match. This applies to = and in.

All-words operators ((.)) work fine in AND. Because (.) checks for individual words — not a contiguous substring — a query like (title (.) "Software Development") AND (title (.) "Software Engineer") matches any title containing all three words “Software”, “Development”, and “Engineer” (e.g. “Software Development Engineer”).

Need companies hiring for both role X and role Y (two different listings)? Run two separate queries and intersect company ids client-side. See Companies indexing both Software Engineers and Account Executives.

Single condition

{
    "filters": {
        "field": "job_details.category",
        "type": "=",
        "value": "Engineering"
    }
}

AND / OR group

{
    "filters": {
        "op": "and",
        "conditions": [
            {
                "field": "company.basic_info.company_id",
                "type": "=",
                "value": 631394
            },
            {
                "field": "job_details.category",
                "type": "=",
                "value": "Engineering"
            },
            {
                "field": "metadata.date_added",
                "type": "=>",
                "value": "2025-01-01"
            }
        ]
    }
}

Array-field filters and grouping

Filtering on array fields

When you filter on a string-array field like company.basic_info.industries, the condition is satisfied if any element of the array matches.For example:

{ "field": "company.basic_info.industries", "type": "=", "value": "Technology, Information and Internet" }

This matches any company whose industries array contains that exact string. Use (.) to match words within any element.

Grouping by array fields

When you group_by on an array field, each array element becomes its own bucket key. A company in two industries contributes one count to each of the two industry buckets — so the sum of bucket counts can exceed total_count for array fields.

Filter operators

Use the table below to pick the right type for each condition. Every operator works on indexed fields only.

Operator	`value` shape	Meaning
`=`	scalar (string/number/boolean)	Exact match.
`!=`	scalar	Not equal.
`<`	scalar (numeric or ISO date)	Less than.
`=<`	scalar (numeric or ISO date)	Less than or equal. Not `<=`.
`>`	scalar (numeric or ISO date)	Greater than.
`=>`	scalar (numeric or ISO date)	Greater than or equal. Not `>=`.
`in`	array of scalars	Field value is any entry in the array.
`not_in`	array of scalars	Field value is none of the entries in the array.
`(.)`	string	Case-insensitive all-words match. Every word in the query must appear somewhere in the field, but not necessarily next to each other or in the same order. `"Software Engineer"` matches `"Software Engineer"`, `"Software Development Engineer"`, and `"Engineer, Software Systems"`. A single word like `"engineer"` also matches `"Engineering Manager"`. Great for broad keyword hunting in `job_details.title` or `content.description`.
`[.]`	string	Case-insensitive exact-phrase match. The words must appear contiguously and in order. `"Software Engineer"` matches `"Senior Software Engineer"` but not `"Software Development Engineer"` (extra word in between) and not `"Engineer Software"` (wrong order). Use `[.]` when you need precision over recall.
`geo_distance`	object (see below)	Geographic radius include. Keeps jobs located within `distance` of a center point. Only valid on `location` (or `location.raw` — both target the same geo point). See Geographic radius filters.
`geo_exclude`	object (see below)	Geographic radius exclude. Removes jobs located within `distance` of a center point. Same value format and field restrictions as `geo_distance`.

Operator footguns.

Use => for greater-than-or-equal and =< for less-than-or-equal — they are not >= and <=.
in and not_in require JSON arrays, not comma-separated strings.
is_null / is_not_null are currently not implemented — request the field via fields and filter for null presence client-side.
geo_distance / geo_exclude only work on location and location.raw. Using them on any other field, or sending a malformed geo value, returns 500 — see Errors.

Geographic radius filters (`geo_distance` / `geo_exclude`)

The value for geo_distance and geo_exclude is an object describing a center point and a radius:

Key	Type	Required	Description
`location`	string	Yes, unless `lat_lng` is provided	Free-form place name (for example `"San Francisco"`). The API geocodes it into coordinates server-side.
`lat_lng`	`[number, number]`	Yes, unless `location` is provided	Explicit `[latitude, longitude]` center point (latitude `-90` to `90`, longitude `-180` to `180`). Takes precedence over `location` when both are sent.
`distance`	number	Yes	Radius around the center point. Must be positive.
`unit`	string	No (default `"km"`)	Distance unit: `"km"`, `"mi"`, `"miles"`, `"m"`, `"meters"`, `"ft"`, or `"feet"`.

Jobs within 25 km of San Francisco:

{
    "filters": {
        "field": "location",
        "type": "geo_distance",
        "value": { "location": "San Francisco", "distance": 25, "unit": "km" }
    },
    "limit": 5
}

US jobs outside a 50-mile radius of New York, combining geo_exclude with other conditions in an and group:

{
    "filters": {
        "op": "and",
        "conditions": [
            { "field": "location.country", "type": "=", "value": "United States" },
            {
                "field": "location",
                "type": "geo_exclude",
                "value": { "location": "New York", "distance": 50, "unit": "mi" }
            }
        ]
    },
    "limit": 5
}

If your center point comes from your own geocoder or a map UI, pass lat_lng directly — for example { "lat_lng": [37.7749, -122.4194], "distance": 25 } — and the server-side geocoding step is skipped.

Common indexed fields

These are the indexed fields most often used in filters, sorts, and aggregations.field. This table is a summary of the most common paths, not an authoritative catalog. For the deeper field catalog — including id semantics, null handling, and bucket metadata — see the full Field reference below.

Company id filter alias. The filterable field path uses the short alias company.basic_info.company_id, but the response shape returns the same integer at company.basic_info.crustdata_company_id. They point to the same value. See Jobs IDs: a quick map.

Job details
Company basic info
Company firmographics
Location
Content, metadata, IDs

Field	Example
`job_details.title`	`"Software Engineer"`
`job_details.category`	`"Engineering"`, `"Sales"`, `"Operations"`, `"Others"`
`job_details.workplace_type`	`"Remote"`, `"Hybrid"`, `"On-site"`, `""`
`job_details.reposted_job`	`true` / `false`
`job_details.url`	`"https://www.linkedin.com/jobs/view/4398377738"`

Field	Example
`company.basic_info.company_id`	`631394`
`company.basic_info.name`	`"Stripe"`
`company.basic_info.primary_domain`	`"stripe.com"`
`company.basic_info.professional_network_id`	`"2135371"`
`company.basic_info.industries`	`["Technology, Information and Internet"]`

Field	Example
`company.headcount.total`	`14522`
`company.headcount.range`	`"5001-10000"`
`company.followers.count`	`1335688`
`company.revenue.estimated.lower_bound_usd`	`500000000`

Field	Example
`location.raw`	`"Melbourne, Victoria, Australia"`
`location.country`	`"Australia"`
`location.state`	`"Victoria"`
`location.district`	`"Southbank"`
`location.city`	`"Melbourne"`

For radius queries (“within 25 km of San Francisco”), filter on location with the geo_distance / geo_exclude operators — see Geographic radius filters.

Field	Example
`content.description`	Full job description text.
`crustdata_job_id`	`41053563`
`metadata.date_added`	`"2026-04-07T11:37:29"`
`metadata.date_updated`	`"2026-04-08T00:00:00"`

Sending a filter on a non-indexed field returns 500 with Unsupported columns in conditions: ['...']. Sending an unsupported group_by field returns a similar 500 listing every supported aggregation field.

Nulls are normal. Nested objects such as revenue.public_markets, location.district, location.pincode, and parts of company.funding can legitimately be null or missing.

Jobs IDs: a quick map

ID	Lives on	Purpose
`crustdata_job_id`	Top-level on each `Job`	Crustdata job identifier. Use it as your dedupe key in your own store.
`job_details.job_id`	Inside `Job.job_details`	Secondary job identifier. It currently mirrors `crustdata_job_id` and is kept for backwards compatibility.
`company.basic_info.crustdata_company_id`	Inside `Job.company.basic_info`	Crustdata company identifier returned on each row.
`company.basic_info.company_id`	Search filter / aggregation path	Indexed alias for the same company identifier. Use this in `filters.field` and `aggregations.field`.

Aggregation bucket metadata

When you group_by on company.basic_info.company_id, each bucket carries a metadata object whose keys use bucket-specific names rather than the Job response dot-paths:

Bucket metadata key	Equivalent `Job` value	Notes
`company_name`	`company.basic_info.name`	Plain company name.
`company_website_domain`	`company.basic_info.primary_domain`	Primary website domain.
`linkedin_id`	`company.basic_info.professional_network_id`	Public-profile identifier returned only inside aggregation buckets.
`crustdata_company_id`	`company.basic_info.crustdata_company_id`	Crustdata company id. Defined in the spec as nullable; the bucket `key` already carries this value.

`company.locations.street_address`	string	✅	—	—	✅	`"354 Oyster Point Blvd, ..."`

Job location (`location.*`)

The city, state, and country fields are derived by geocoding the raw location string, so they carry normalized place names rather than the raw text’s wording. city can be an empty string "" when the raw location resolves to an area broader than a city (for example "San Francisco Bay Area" geocodes to state: "California" with an empty city).

Path	Type	Filter	Sort	Group	Return	Example
`location`	geo point	✅ (geo only)	—	—	—	Geographic radius filters
`location.raw`	string	✅	—	—	✅	`"Melbourne, Victoria, Australia"`
`location.city`	string	✅	—	—	✅	`"Melbourne"`
`location.district`	string	✅	—	—	✅	`"Southbank"`

`location.country`	string	✅	—	✅	✅	`"Australia"`
`location.pincode`	string	—	—	—	✅	`"3006"`

Country values are geocoded and normalized. location.country carries normalized full country names ("United States", "United Kingdom"). A small share of rows still carries a residual variant such as "United States of America". When completeness matters, match both with in, or pre-discover the exact indexed values by running a group_by on location.country.

Content (`content.*`)

Path	Type	Filter	Sort	Group	Return	Example
`content.description`	string	✅	—	—	✅	`"Stripe is a financial infrastructure..."`

Use the (.) operator on content.description to find listings by technology, skill, or keyword.

`metadata.date_added`	string (ISO 8601)	✅	✅	—	✅	`"2026-04-07T11:37:29"`
`metadata.date_updated`	string (ISO 8601)	✅	✅	—	✅	`"2026-04-08T00:00:00"`

Null, blank, and sparse field behavior

Most Job fields are nullable in the spec and can legitimately be absent or empty.

Null or missing — the field is not present on a given Job.
Blank string "" — the field was present but had no indexable value (common for job_details.workplace_type). Treat blank as “unspecified”, not as the same thing as null.
Sparse nested objects — company.funding, company.revenue, and company.competitors are often missing for smaller or private companies.
is_null / is_not_null operators are currently not implemented — request the field via fields and filter for null presence client-side.

Errors

Status	`error.type`	Meaning
`400`	`invalid_request`	Request body failed validation — `limit` out of range, a missing required key, or an unrecognized parameter (for example sending `column` instead of `field`).
`401`	`unauthorized`	The `Authorization` header is missing, malformed, or contains an invalid API key.
`500`	`internal_error`	The query could not be executed — including when a filter or aggregation references an unsupported field, when a `geo_distance`/`geo_exclude` value is malformed or used on a non-geo field, or when a geo `location` string cannot be resolved to coordinates. Also covers transient server errors; retry after a short delay.

Every error — including 401 — uses the same nested envelope: { "error": { "type", "message", "metadata" } }. Branch on error.type rather than string-matching message.

{
    "error": {
        "type": "invalid_request",
        "message": "'limit' must be at most 1000. Got 5000.",
        "metadata": [
            {
                "field": "limit",
                "type": "less_than_equal",
                "message": "'limit' must be at most 1000. Got 5000."
            }
        ]
    }
}

Pagination & sorting

How to paginate, sort, select fields, and aggregate results in Search Jobs. For worked examples, see Examples. For filter grammar, operators, and the full field catalog, see Reference.

Replace YOUR_API_KEY in each example with your actual API key. All requests require the x-api-version: 2025-11-01 header.

Sorting

sorts is an ordered array. Each item has a field and order ("asc" or "desc"). Sorts apply in array order — the first sort is the primary key, the second breaks ties, and so on.

{
    "sorts": [
        { "field": "metadata.date_added", "order": "desc" },
        { "field": "company.headcount.total", "order": "desc" }
    ]
}

Sort allowlist is narrower than filter allowlist. Sort only works on numeric, date, and a small set of scalar fields. Sorting on text fields like job_details.title, job_details.category, or company.basic_info.name returns Unsupported columns in conditions.

Sortable fields

The following indexed fields are verified sortable:

crustdata_job_id
metadata.date_added
metadata.date_updated
company.headcount.total
company.followers.count
company.revenue.estimated.lower_bound_usd
company.funding.last_fundraise_date
company.funding.num_funding_rounds
relevance — only valid when a text query is present in filters (maps to the text-match score); sorting on it without a text condition returns 400

Common sort choices:

Newest postings first — { "field": "metadata.date_added", "order": "desc" }
Biggest companies first — { "field": "company.headcount.total", "order": "desc" }
Most followed companies first — { "field": "company.followers.count", "order": "desc" }
Most funding rounds first — { "field": "company.funding.num_funding_rounds", "order": "desc" }

Pagination

Pagination is cursor-based. Each response returns a next_cursor (or null when you reach the end). To fetch the next page, resend the original request body with cursor set to the previous next_cursor.

Fetch the first page

Omit cursor and set limit to your page size (max 1000).

Walk forward

Take next_cursor from the response and pass it back as cursor in the next request. Keep filters, sorts, and fields identical — if you change them, the cursor becomes meaningless.

Stop when `next_cursor` is null

A null cursor means you’ve reached the end of the result set.

Consistency between pages

Best-effort, not strict snapshot. A cursor is consistent with respect to the filter, sort, and field selection you sent on the first page, so the same query will keep paging forward over a coherent result stream. However, because the underlying indexed dataset is continuously updated, new jobs indexed between page requests can cause minor drift in total_count and in the exact position of individual rows. Treat pagination as best-effort, not a strict snapshot.For bulk exports where every row matters:

Constrain your filter to a bounded date window (for example metadata.date_added >= 2025-01-01 AND < 2025-07-01) so newly indexed jobs outside the window do not affect the walk, and
Re-run the full walk periodically and diff against the prior snapshot using crustdata_job_id as the dedupe key.

Dataset freshness and lifecycle

What the indexed Jobs dataset represents. The Search Jobs dataset is a rolling index of job listings discovered from the web, refreshed on an ongoing basis. Each row has:

metadata.date_added — when Job was posted.

Closed or removed listings are not guaranteed to disappear from the index immediately. To approximate “currently hiring” queries, filter on a recent metadata.date_added window (for example, within the last 30 days) and pair it with the hiring company’s firmographics. For alerting or repeated exports, keep your date windows bounded and dedupe rows with crustdata_job_id.

Date filter semantics

Dates and timezones. When you pass a date-only value like "2025-01-01", the backend interprets it as 2025-01-01T00:00:00 in UTC. Ranges using => are inclusive of the boundary and < is exclusive, so "metadata.date_added" >= "2025-01-01" AND < "2025-07-01" covers every listing indexed between Jan 1 (inclusive) and Jul 1 (exclusive) in UTC. Pass full timestamps like "2025-01-01T08:00:00" when you need finer precision.

}

Field selection

Use fields to return only the dot-paths you need. The top-level groups are crustdata_job_id, job_details, company, location, content, metadata. You can request:

A whole group — "company" returns every company.* sub-object.
A sub-object — "company.basic_info" returns only the basic info block.
A single field — "company.basic_info.name" returns just the name.

{
    "fields": [
        "job_details.title",
        "job_details.url",
        "company.basic_info.name",
        "company.basic_info.primary_domain",
        "location.raw",
        "metadata.date_added"
    ]
}

Recommended default field set for most dashboards:

["job_details.title", "job_details.category", "job_details.url",       "company.basic_info.name", "company.basic_info.primary_domain",       "location.raw", "metadata.date_added"]

Aggregations

Aggregations let you roll up results without returning individual job rows. Set limit: 0 when you only want aggregation output. Two types are supported:

count — returns the total number of jobs matching filters.
group_by — buckets the results by field and returns per-bucket counts.

`AggregationRequest` schema

Field	Type	Required	Description
`type`	string (enum)	Yes	`"count"` for a simple total, `"group_by"` to bucket by `field`.
`field`	string	Required for `group_by`	Dot-path to group by. Must be in the Groupable fields allowlist.
`agg`	string (enum)	Required for `group_by`	Sub-aggregation inside each bucket. Currently only `"count"` is supported.
`size`	integer	No (default `100`)	Maximum number of buckets to return. Min `1`, max `1000`.

Each AggregationResponseItem echoes type and field, then carries:

value (integer) — populated for count aggregations. The total match count.
buckets (array) — populated for group_by aggregations. Each bucket has a key, count, and a metadata object whose keys depend on the grouped field. See Aggregation bucket metadata.

You can include multiple aggregations in a single request; the response returns them in aggregations[] in the same order you sent them.

Groupable fields

group_by.field is restricted to the following indexed fields:

company.basic_info.company_id
company.basic_info.crustdata_company_id
company.basic_info.industries
company.basic_info.primary_domain
company.funding.last_round_type
company.headcount.range
company.locations.country
job_details.category
job_details.title
job_details.workplace_type
location.country

Sending any other field returns 500 with Unsupported aggregation field: '...'. Supported: ....
