Colin Goodheart-Smithe b717ad8eb6 Enable option to use request cache for size > 0
Previously if the size of the search request was greater than zero we would not cache the request in the request cache.

This change retains the default behaviour of not caching requests with size > 0 but also allows the `request_cache=true` query parameter
to enable the cache for requests with size > 0
