Hi all, I'm a relative newcomer to Solr, and I'm trying to use it in a project of mine. I need to do a function query (I believe) to filter the results so they are within a certain distance of a point. For this, I understand I should use something like sqedist or hsin, and from the documentation on the FunctionQuery page, I believe that the function is executed on every "row" (or "record", not sure what the proper term for this is). So, my question is threefold really; are those functions the ones I should be using to perform a search where distance is one of the criteria (there are others), and if so, does Solr execute the query on every row (and again, if so, is there any way of preventing this [like subqueries, though I know they're not supported])?
Sorry if this is a little confusing… any help would be greatly appreciated :) Thanks, Oliver
