Solr edismax. How to retrieve the fields that gave the query result

I'm querying mulitple fields using the qf param. But I'm wondering how I can retrieve the field that gave the result.

Example(not a real example):

      q={!edismax qf='tag content'}("tablet")AND("pc")

Field values:

      doc1:
           tag: tablet
           content: The test has failled. Use a pc instead.
      doc2:
           tag: tablet pc
           content: The test has worked.

As a result both documents will be returned because they both have the tablet and pc in their tag/content. Is it possible to know that doc2 had both hits in tag and doc1 only had 1 hit in tag and 1 in content? Debugquery doesn't seem to provide information about this.

I know I can increase the importance of a searchfield using the qf boost.

Ok based on your response to my question.

Unfortunately, there is no way Solr currently returns which fields matched the query as part of your defaulting result docs . If the query is simple, looping over the returned stored fields is probably your best bet. Highlighting is be an option too.

There are couple of other options suggested here : http://grokbase.com/t/lucene/solr-user/117nkf36nq/determine-which-field-term-was-found

you can either:

  1. use Highlighting
  2. ask for debug info with debugQuery=true and parse the scoring info to find out.

I think 1 is easier, but it imposes some constraints on your fields (they must be stored for example)
