[KinoSearch] Field-specific terms vs. query filter?

[Larry Leszczynski]

Hi -

I'm working with an index that has a "category_id" field, and I need 
to filter search results based on specific categories which the user 
shouldn't be able to see.  Right now I'm taking the user's original 
query and appending a lot of booleans with field-specific terms, e.g. 
a search for "foo" turns into something like "(foo) AND NOT 
(category_id:1) AND NOT (category_id:7) AND NOT ...".

Is there any advantage to building up a Boolean query for just the 
category_id parts, and using that as a query filter instead?  I won't 
necessarily be able to cache/reuse the query filter.  Is there a 
better way in general to do this?

Related question:  Assuming the category_id field is indexed but not 
analyzed, is a field-specific term going to do an exact match?  I.e. 
will "category_id:1" match just "1", or will it also match "10"?


Thanks!
Larry
