API ReferenceQuery

Query - v3

Search indexed files and return source chunks with optional document, metadata, region (bounding boxes), relation, and related chunk context. **Compared with v2:** this response uses `results[].text`, supports explicit include controls, and returns structured rerank details. **Filter keys are top-level field names.** Never nest them under `metadata` or `custom_metadata`. Use `{"policy_area": "payments"}`, not `{"custom_metadata": {"policy_area": "payments"}}`. Operators are `$`-prefixed (`$gte`, not `gte`). See the [Advanced Querying guide](/guides/advanced-querying) for the full filter reference.

Path parameters

collection_namestringRequired

Request

This endpoint expects an object.
querystringRequired
Natural-language search query.
limitintegerOptional1-100Defaults to 10
Maximum number of ranked chunks to return.
filterobject or nullOptional
Document metadata filter expression. Keys are top-level field names, never nested under `metadata` or `custom_metadata`. A bare value is an implicit `$eq` (`{"policy_area": "payments"}`). Supported operators: `$eq`, `$ne`, `$gt`, `$gte`, `$lt`, `$lte`, `$in`, `$nin`, and the logical `$and` and `$or`. `$in` and `$nin` take a list; every other operator takes a scalar. Max nesting depth is 10. To scope a query to specific documents, filter on `file_id` with `$in`. See the [Advanced Querying guide](/guides/advanced-querying) for more.
rerankbooleanOptionalDefaults to false
Whether to request reranking. Multimodal collections may apply reranking even when this is false.
includeobjectOptional
Controls which optional result objects are included in the response.
relation_typeslist of strings or nullOptional
Optional relation type filter when `include.relations` or `include.related_chunks` is enabled.
relation_directionenumOptionalDefaults to outgoing
Which graph edge direction to include for relation context.
