Field-specific terms vs. query filter?
|
|
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
