Xapian discuss - Jul 2006 - (Solved) Re: How to configure omega.cgi to search multiple flint dbs?

Folks,

OK found it, omega.cc looks for multiple DB definitions and adds it to the
search list. If the dbs are only one directory lower (e.g. not in default as in
beta/default, but only "beta"), then modifying database_dir setting as
follows will work:

database_dir /svr/hda1/xapian

then,

./omega.cgi 'P=pda' FMT='xml' DB="beta"
DB="gamma" DB="delta" HITSPERPAGE=1

...provides a roll up of the queries, and summaries results. (Super!)

Thanks,
OSC

You can also specify multiple databases in one DB parameter using this
syntax: DB=beta/gamma/delta 

Another approach is to use a "stub" database, which is just a text
file
listing one or more databases, so you can then just refer to a
pre-specified combination of databases using DB=default (or DB=whatever)
in Omega.  The stub database format is documented here:
