The SOQL syntax USING LOOKUP was announced and then removed from the Winter 15
release notes and appears not to have been subsequently announced nor released.
SELECT Id, Name
USING LOOKUP Account.ParentContact__c
BIND ParentId = '001000000000000'
appears to work, and seems to be designed to be used in conjunction with the dependent fields described by the filteredLookupInfo
to be able to dynamically build your own lookup dialog. The alternative method of using the metadata api to retrieve and implement the filter criteria is far more involved.
It'd be great to see this functionality finalised and release, or at least documented along with any known limitations.
