If you use radio buttons, then you can only select one database at a time
anyway. This can be done using the config input parameter to select the
one configuration file for the desired database.

On the other hand, if you use checkboxes or a select multiple list, then
you'd need Rajendra's patch for multiple database searching:

    http://www.htdig.org/htdig3-dev/2000/03/0117.html

It's already in the 3.2 code base, as Geoff pointed out. For 3.1.x, there
is a patch available by following the above link, but it's for 3.1.3, so
I don't know how smoothly it'll apply to 3.1.5.

The other option is to use htmerge to build up some combined databases
for all the combinations you're likely to need, and select them as single
databases using a select list or radio buttons.
