Look at the first few Google results for "symbolic link".
If your search results for a particular case are stored in
resultXYZZY12345.dbf, and your master shapefile with all possible
geocoded locations are in master.shp/shx/qix, you would do this:
ln -s master.shp resultXYZZY12345.shp
ln -s master.shx resultXYZZY12345.shx
ln -s master.qix resultXYZZY12345.qix
and then you could use resultXYZZY12345 as any other shapefile in Mapserver.
You're really at the point where you need to just dig in and try some
of these things. Run some test cases, benchmark them, see what works
fastest for your own situation.
Please report back to the group--someone else may have a similar
question someday.

There's no real notion of a JOIN in Shapefiles. You have to copy the
geometry files and generate a new .DBF file. A cheaper way to do
that, though, is to use a symbolic link instead of a completely new
copy, for each of the geometry files.
i searched the website- didn't get anywhere with symbolic link.
anyway what's the fastest join- csv? dbf? xml? ? if xml i'd use the
gmaps way- 1 search database 2 results as xml 3 read xml with ajax
and 4 show points.
about wms- since wms can filter data, maybe i'd set one up that
filters based on the results? big maybe ;)
jzs
