I don't think there is a way of identifying which of the values of a
multivalued field matched. But... I haven't checked the code to be
absolutely certain whether their isn't some expert way.
Also, realize that multiple values could match, such as if you queried for
"B*".

Subject: Multi-value fields in Lucene 4.1
Hi,
If I index several similar values in a multivalued field (e.g. many authors
to one book), is there any way to know which of these matched during a
query?
e.g.
Book "The art of Stuff", with authors "Bob Thingummy" and "Belinda
Bootstrap"
If we queried for +(author:Be*) and matched this document, is there a way of
drilling down and identifying the specific sub-field that actually triggered
the match ("Belinda Bootstrap") ? I was wondering what the lowest
granularity of matching actually is - document / field / sub-field ...
I am happy to index with term vectors and positions if it helps.
Thanks,
- Chris
