 ### Matching strategy
 
-`matchingStrategy` gives you the possibility to choose how Meilisearch should handle the presence of multiple query words.
+`matchingStrategy` gives you the possibility to choose how Meilisearch should handle the presence of multiple query words, see [documentation](https://docs.meilisearch.com/reference/api/search.html#matching-strategy).
 
 For example, if your query is `Hello world` by default Meilisearch returns documents containing either both `hello` and `world` or documents that only contain `hello`. This is the `last` strategy, where words are stripped from the right.
 The other strategy is `all`, where both `hello` and `worlds` **must** be present in a document for it to be returned.
