Delete Vectors

Delete documents from a vector store by document IDs or metadata filter criteria.

Delete by IDs: Provide an array of document IDs to delete specific documents. Non-existent documents are silently skipped.

Delete by Filter: Use metadata filters to delete all documents matching the specified criteria (e.g., delete all documents where status: "archived"). The filter must specify at least one condition and cannot be empty. To delete all documents, use the drop endpoint instead.

Filter Operators: Supports MongoDB-style operators including equality ({"field": "value"}), comparison ($gt, $gte, $lt, $lte, $eq, $ne), logical ($and, $or, $not), and membership ($in, $nin). Only indexed metadata fields can be used for filtering.

Best Practice: Use the count endpoint with the same filter to preview the number of documents that will be deleted before executing the deletion operation.
