+ title: Disable cross-cluster functionality for `_fleet/_fleet_search`
+ area: Search
+ details: |-
+ This endpoint is largely used for local searches only and is not compatible with true cross-cluster searches where
+ arbitrary number of indices and remotes can be specified. Although it is meant to accept an index parameter that
+ denotes a single searchable target, such a limitation can be bypassed through various means.
+
+ Keeping in view this endpoint's stated intent and future scope, cross-cluster functionality is being explicitly disabled.
+ impact: |-
+ This endpoint will no longer accept remote indices. Should one be provided, a top-level error is returned with
+ an appropriate explanation.

 We don't recommend this legacy query type for _new_ projects. Use the match query (with [QueryDSL](/reference/query-languages/query-dsl/query-dsl-match-query.md) or [ESQL](/reference/query-languages/esql/functions-operators/search-functions.md#esql-match)) instead. The semantic query remains available to support existing implementations.

-The `semantic` query type enables you to perform [semantic search](docs-content://solutions/search/semantic-search.md) on data stored in a [`semantic_text`](/reference/elasticsearch/mapping-reference/semantic-text.md) field.
+The `semantic` query type enables you to perform [semantic search](docs-content://solutions/search/semantic-search.md) on data stored in a [`semantic_text`](/reference/elasticsearch/mapping-reference/semantic-text.md) field. This query accepts natural-language text and uses the field’s configured inference endpoint to generate a query embedding and match documents.
 
+For an overview of all query options available for `semantic_text` fields, see [Querying `semantic_text` fields](/reference/elasticsearch/mapping-reference/semantic-text.md#querying-semantic-text-fields).
+
+## Inference endpoint selection
+
+The target field of `semantic` query must be mapped as `semantic_text` and associated with an inference endpoint. At query time, the inference endpoint is chosen as follows:
+- If `search_inference_id` is defined, the semantic query uses that endpoint to embed the query.
+- If no `search_inference_id` is defined, `inference_id` is used for both indexing and search.
+- If no endpoint is specified at mapping, `inference_id` defaults to `.elser-2-elasticsearch`.
+
+The underlying vector type (dense or sparse) is determined by the endpoint automatically. No extra query parameters are required.
