There is `M-x tags-search RET regexp RET'.  This searches for tags
matching `regexp' and it can iterate through more than one tag table.
Once a single match is found you can find the next one with `M-,' and
repeat until you have finished going through all the matches, or you
have found what you were looking for.

The temporary buffers that have no matches are closed as tags-search
goes through the motions, so you are finally let with a buffer list
like (a sample from my iswitchb buffer list):

: MR Name                    Size Mode             Filename/Process
: -- ----                    ---- ----             ----------------
:[ Default ]
:    setup.c                18454 C/l              /work/foo/src/setup.c
:    net.c                  18077 C/l              /work/foo/src/net.c
:  % foo                     2947 Dired by name    /work/foo/
: *  *Messages*              5070 Fundamental

The buffers under `/work/foo' are those that had at least one match.
