 * **Index time**: Synonyms are applied when the documents are indexed into {{es}}. This is a less flexible alternative, as changes to your synonyms require [reindexing](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-reindex).
 * **Search time**: Synonyms are applied when a search is executed. This is a more flexible approach, which doesn't require reindexing. If token filters are configured with `"updateable": true`, search analyzers can be [reloaded](https://www.elastic.co/docs/api/doc/elasticsearch/operation/operation-indices-reload-search-analyzers) when you make changes to your synonyms.

 You can specify the analyzer that contains your synonyms set as a [search time analyzer](../../../manage-data/data-store/text-analysis/specify-an-analyzer.md#specify-search-analyzer) or as an [index time analyzer](../../../manage-data/data-store/text-analysis/specify-an-analyzer.md#specify-index-time-analyzer).
