Xapian discuss - Jan 2006 - Trying to get omegascript configured to support multiple dbs

I made the following changes to the query template.  Hoping that it 
would let me select from a couple of databases.

<INPUT NAME=P VALUE="$html{$query}" SIZE=65>
<INPUT TYPE=SUBMIT VALUE="Search" BORDER=0>
<hr>
<input type="checkbox" name="DB"
value="default"
$if{$eq{$cgi{DB},default},CHECKED} > Default<br>
<input type="checkbox" name="DB" value="tst.db"
$if{$eq{$cgi{DB},tst.db},CHECKED} > Test<br>
<hr>


Well it does sort of.  Two problems.  It always looks for the default 
even if I've got it unchecked.  The other problem is if I have both of 
them checked, when I return from the query, it resets the test 
checkbox.  I suspect that's because the cgi parameter, DB is a list and 
I don't know how to say "if tst.db is in the DB list, then ...".

Suggestions?

Thanks,
Jim.

Note that $cgi{DB} will pick an arbitrary DB parameter if there's more
than one.  You want $cgilist{DB} which will return all the values, as
a tab-separated list.

But there's no obvious way to see if a list contains a particular value
which is what you then need to be able to do.  Something like
$find{LIST,STRING} to return the offset into the list, or the empty
string if not present.  I'll see if I can manage to implement that
before the next release.

A related issue to bear in mind is what happens if there's no DB
parameter (in which case Omega will search the database "default").

Cheers,
