# Ensure Namespace Payload Indexes

`POST /v1/namespaces/{namespace_identifier}/ensure-indexes`

(Re-)create the namespace's declared payload indexes in the vector store, including FULLTEXT/BM25, idempotently. ZERO-EXTRACTION: registers any missing indexes and backfills existing documents WITHOUT triggering any ingest or re-extraction. Use to repair a missing index (e.g. a FULLTEXT index that failed to register) or as a self-serve re-index tool — no re-ingest, no GPU.

READING THE RESPONSE: `ensured` lists indexes the call confirmed present — it does NOT mean they were newly built, and an already-registered index is a cheap no-op on the shard. `rebuilt` is populated only with `force_rebuild=true`, which is the case that does real work. `skipped` is normally empty because the store reports an idempotent no-op as success rather than an error, so an empty `skipped` does not imply the rest were created. `created` is a deprecated alias of `ensured` + `rebuilt`.

COST: a plain ensure is cheap. `force_rebuild=true` applies to EVERY declared index, drops and rebuilds each from the complete store, and for FULLTEXT fields first hydrates the full payload store — no GPU, but real shard CPU and memory proportional to the corpus. Size it before running on a large or memory-constrained namespace.

## Path parameters

- `namespace_identifier` string, required — Either the namespace name or namespace ID

## Query parameters

- `force_rebuild` boolean — Drop and rebuild each index from the complete store instead of the normal idempotent ensure. Use to repair a FULLTEXT/BM25 field that registered empty during a cold shard warmup (no cluster access needed — the shard grpc is in-cluster only, so this API is the sole trigger). Default false.
