+> More info about match query is in the [official elasticsearch docs][1]
+
+A family of match queries that accept text/numerics/dates, analyzes it, and constructs a query out of it.
+
+## Simple example
+
+```JSON
+{
+    "match" : {
+        "message" : "this is a test"
+    }
+}
+```
+
+In DSL:
+
+```php
+$matchQuery = new MatchQuery('message', 'this is a test');
+
+$search = new Search();
+$search->addQuery($matchQuery);
+
+$queryArray = $search->toArray();
+```
