+### Find traces with arrays
+
+TraceQL automatically queries data contained in arrays.
+Support for arrays is available in vParquet4 and on.
+
+If `span.foo` is an array and contains the value `bar`, then it will be found by this query.
+
+```
+{ span.foo = "bar" }
+```
+
+You can use regular expressions to match multiple values of array `{span.http.request.header.Accept=~"application.*"}` and get all values of the array with `.*` regular expression.
+
+```
+{span.http.request.header.Accept=~".*"}
+```
+
 ### Use structural operators
 
 Find traces that include the `frontend` service, where either that service or a downstream service includes a span where an error is set.
