Any suggestions to try out on this?  I'm just worried about performance 
impacts as it takes a fair amount of time to do a CONTAINS search on my 
small install...  I don't have even any rough numbers, but I could get 
some if it would make a difference.

For those out there with larger installs, can you give the list some 
feedback on the search performance.  Specifically the differences 
between the BEGINS WITH and CONTAINS searches, as those are the most 
likely to be used (there aren't a lot of EXIF data fields that lend 
themselves to exact search matches...).
