+
+You can use the reload search analyzers API
+to pick up changes to synonym files
+used in the <<analysis-synonym-graph-tokenfilter,`synonym_graph`>>
+or <<analysis-synonym-tokenfilter,`synonym`>> token filter
+of a <<search-analyzer,search analyzer>>.
+To be eligible,
+the token filter must have an `updateable` flag of `true`
+and only be used in search analyzers.
+
+[NOTE]
+====
+This API does not perform a reload
+for each shard of an index.
+Instead,
+it performs a reload for each node
+containing index shards.
+As a result,
+the total shard count returned by the API
+can differ from the number of index shards.
+
+Because reloading affects every node with an index shard,
+its important to update the synonym file
+on every data node in the cluster,
+including nodes that don't contain a shard replica,
+before using this API.
+This ensures the synonym file is updated
+everywhere in the cluster
+in case shards are relocated
+in the future.
