map a search: best strategy?

[Hal Mueller]

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.
