Start feeding query matches back to the caller before the entire search is
2001-03-17 Jon Trowbridge <trow@ximian.com> * backend/pas/pas-backend-file.c (pas_backend_file_search): Start feeding query matches back to the caller before the entire search is complete; this gives us some "instant feedback" rather than causing evolution to totally lock up... svn path=/trunk/; revision=8792
