Opportunity for optimization on invalid query to REST API Search Controller

Here we see get_items executes a query and gets a list of $ids. Then it loops through all $ids to prepare the response. And then it checks the total number of records to see if the requested page is larger than the number of pages available.

This is a proposal to check $max_pages before the response preparation, to avoid the loop if the request is pre-destined to return an error anyway.

This would only provide a performance benefit on invalid queries. But looking up at line 115, function get_items_permission_check always returns true. I can imagine a DOS where a large number of search queries are queued up just to keep a system busy.
