If I have an arbitrarily complex query that uses ORs, something like: q=(simple_fieldtype:foo OR complex_fieldtype:foo) AND (another_simple_fieldtype:bar OR another_complex_fieldtype:bar)
I want to know which fields actually contributed to the match for each document returned. Something like: docID=1, fields_matched=simple_fieldtype,complex_fieldtype,another_complex_fieldtype docID=2, fields_matched=simple_fieldtype,another_complex_fieldtype My basic use case is that I have several copyField'ed variations on the same data (using different complex FieldTypes), and I want to know which variations contributed to the document so I can conclude things like "Well, this document matched the field with the SynonymFilterFactory, but not the one without, so this particular document must've been a synonym match." I know you could probably lift this from debugQuery output, but that's a non-starter due to parsing complexity and query performance impact. I think you could edge into some of this using the HighlightComponent output, but that's a non-starter because it requires fields be stored=true. Most of my fieldTypes are intended solely for indexing/search, and make no sense from a stored/retrieval standpoint. And to be clear, I really don't care about which terms matched anyway, only which fields. If there's an easy way to get this, I'd love to hear it. Otherwise, I'm mostly looking for a head start on where to go looking for this data so I can add my own Component or something - assuming the data is even available in the solr layer? Thanks.
