What I am saying is we could probably do it the other way round: Use
the same backend for the functionality of locate, id-util and in

With just a little bit tweaking it is there in idxsearch.el in nXhtml.
(Though it requires an indexed search engine (which should be there
already in most cases I believe) and ruby.)
