Enonic version: 6.4.2
OS: Mac and Linux
The documentation briefly mentions Search Filter & query-filter:
http://xp.readthedocs.org/en/stable/developer/search/overview.html#filter-query-filter
But the query documentation does not include it:
http://repo.enonic.com/public/com/enonic/xp/docs/6.4.2/docs-6.4.2-libdoc.zip!/module-lib_xp_content.html#.query
Not yet implemented, or simply not yet documented?
