Erik, Thanks for the response. The issue with
(original query) AND (field:foo^boost1 OR field:bar^boost2 OR field:baz^boost3) means that the 'field' must have a value for the query to succeed, which isn't always the case: there could be documents where 'field' has no value. So unless I understand the BooleanQueries this would be a non-starter. Or am I missing something?
