How to know which value matched in multivalued field

[Takashi Sasaki]

Hi Solr experts,

I have multivalued location on RPT field.
Is there a way to know which location matched by query?

sample query:
&q=:&fq={!bbox sfield=store}&pt=45.15,-93.85&d=5

Of course I can recalculate on the client side,
but I want to know how to do it using Solr's features.

Solr version is 7.3.1.

Thanks,
Takashi Sasaki
