Thanks for the reply. Let's say that I have a location code field in the document. Say there are 2000 indexed documents that have various location codes. When a user searches, she specifies her own location, as well as the maximum radius that she wants the distance to be, in addition to other search fields that she may specify.
In order to satisfy this scenario, I am thinking about performing the search using all the other fields normally, but use a distance to dynamically filter out unwanted results. This way the distance calculation performs filtering, and the relevancy from other search fields does not change... Let me know if this makes sense to you.
