Hi,
Please clarify my doubts.
What's the use of storing proximity data internally while
indexing? Is
it only for score calculation or any other additional purpose?
How lucene handles phrase query? Whether it's depend on
proximity data
of phrase terms or any other?

Do you speak of term offsets or term positions?

Hi,
I'm speaking about term positions.
In Lucene File Format, the .prx file contains the lists of
positions
that each term occurs at within documents.
I asked what's the purpose of this .prx file?
It is generally used for phrase/span queries.
Also how phrasequery handled?
