+[[combined-fields-usage]]
+=== Combined Fields Usage
+
+The `combined_fields` query supports searching multiple text fields as if their contents had been indexed into one combined field. It takes a
+term-centric view of the query: first it analyzes the query string into individual terms, then looks for each term in any of the fields.
+
+See the Elasticsearch documentation on {ref_current}/query-dsl-combined-fields-query.html[combined fields query] for more details.
