+ Filters an input object or list using the [jq](https://stedolan.github.io/jq/) language, as implemented by [gojq](https://github.com/itchyny/gojq).
+
+ Any JSON datatype may be used as input (NOTE: strings are not JSON-parsed but passed in as is).
+ If the expression results in multiple items (no matter if streamed or as an array) they are wrapped in an array.
+ Otherwise a single item is returned (even if resulting in an array with a single contained element).
+
+ JQ filter expressions can be tested at https://jqplay.org/
