What is registered query in MarkLogic

Solution

MarkLogic has a pretty good explanation in the Search Developer's Guide:

If you use the same complex cts:query expressions repeatedly, and if you are using them as an unfiltered cts:query constructor, you can register the cts:query expressions for later use. Registering a cts:query expression stores a pre-evaluated version of the expression, making it faster for subsequent queries to use the same expression. Unfiltered constructors return results directly from the indexes and return all candidate fragments for a search, but do not perform post-filtering to validate that each fragment perfectly meets the search criteria.

Here's the HTML version of that guide: http://docs.marklogic.com/guide/search-dev/cts_query. It's very thorough and includes examples.
