Hi again, I have a small problem with using a boost query, which is that I would like documents found in the boost query to be returned even if the main query does not include those results. So what I am effectively looking for is an OR between the dismax query and the boost query, rather than a required main query or'd with the boost query. Does anything currently exist which can facilitate this?
For example, currently my parsed query looks something like this, where the domain, page_title and body_text fields are part of the dismax query, and user_id is part of the boost query: +DisjunctionMaxQuery((domain:maps^4.0 page_title:map^2.0 | body_text:map)~0.01) user_id:12^5.0 Whereas I would like it to look like this: +(DisjunctionMaxQuery((domain:maps^4.0 page_title:map^2.0 | body_text:map)~0.01 user_id:12^5.0) This is because I want all documents with user_id:12 to be returned, even if there are no keyword matches. I also want all documents with keyword matches to be returned, even when the user_id doesn't match, so I can't just switch the query and the boost query. Any ideas? Thanks for your time.
