you discovered some secret possibilities of p.mapper 3.1 ;-) The search
is completely re-written and offers new functions, none of them
documented so far. They are not fully tested in real applications, just
in a separate testing environment. And some changes due to 'fine tuning'
might appear.
What you ask for is possible with the current code, one has to specify
the dBase file (usually the dbf part of a shapefile), it can also be a
text or database to be used for the suggest data (similar for select
options) and it supports regex's. I will set up a simple example in due
time, so one can take this as a base. In order to have it running
correctly and avoiding errors for wrong settings, an XML schema would
make sense, but that's even farer away...
