Finding out which fields matched the query
Hello!

I’m a MSCS student from BU and learning to use Lucene. Recently I try to
output matched fields by one query. For example, for one document, there
are 10 fields and 2 of them match the query. I want to get the name of
these fields.

I have tried using explain() method and getting description then regex.
However it cost so much time.

I wonder what is the efficient way to get the matched fields. Would you
please offer some help? Thank you so much!

Best regards,
Yichen Sun

What is the reason you need the matched fields? Maybe your use case can be solved using sth completely different than knowing which fields were matched.
