RE: How to find out which fields a search came from

Highlighting is the way to go.  Note, you have options to make it better suit your application.  e.g. You can control the delimiters the highlighter uses.   You can also choose from a couple different implementations.   We have been able to use the highlight results, as is, to pull data from fields which match the query.  Works fine.

That said, Damian Dykman was asking for highlight results in object form recently.  And Simon (Rosenthal?) responded with a link to SOLR-4722, which includes a patch for such a highlighter.   Might be worth a look.

Subject: How to find out which fields a search came from

Hi folks,

When I get my hits back from Solr, is there a way to find out into which fields my search term matched in?

For example, if the indexed document is:

  doc_1:
    title = From Russia with Love
    director = Terence Young
    starting = Sean Connery, Redro Amendariz, Lotte Lenya,
    music_by = John Barry
doc_2:
    title = Goldfinger
    director = Guy Hamilton
    starting = Sean Connery, Honor Blackman, Gert Frobe
    music_by = John Barry
doc_3:
    title = Skyfall
    director = Sam Mendes
    starting = Daniel Craig, Javier Bardem, Ralph Fiennes
    music_by = Thomas Newman

If my search term is "love john barry guy", Solr will tell me I have a hit in doc_1 and doc_2.  But what I also need to know in which field my search terms match.  How can Solr tell me that doc_1::title and doc_1::music_by and doc_2::music_by are where my search terms matched?

It looks to me that the highlighter does this, but I need this feature without enabling the highlighter.

Thanks!

Steve
