Ah, I see the problem. You're mixing boolean-indexing with non-boolean 
usage. No, the users=1 ... n is not the correct way to index booleans, 
the entire string will be the boolean value (and therefore in some cases 
way too long).
The users=1, users=2 etc way is correct to specify multiple boolean values.

I reread this now. field=users index=XU should be working and mappable 
in the Omega-template. Then, you should be able to map that and to 
search for it using a user:...-like statement as part of your searchquery.
But your last scriptindex (the one you sent in your e-mail) contained 
boolean=XU, not index=XU.

When you index them as booleans, you cannot use them in the searchquery 
itself, but you need to specify (multiple) B=XU{uid}-like cgi-values. On 
the commandline, it'd be something like this:
./omega P="your query here" B=XU1 B=XU4

Here uid 1 and 4 would be OR-ed.

PS, don't forget to reindex your DB when you want to change the 
indexing-format.
