Does the Solr provide hightlight token position in the field?
Does the hightlight can provide the exact position of the query
For instance:
MSAQLRKPTA*RVCES*CGRAEHWDDDLEAWQIARTDGTKQVGSPHCLHEWDINGNFNPVAMDD
I want to know the Position of "R" in the highlight token.
I want to do the secondary query based on the position, Thanks!

Thanks! I look at the api carefully before, but not very sure.
So,it seems that the highlighter might not be helpful.
I am considering alternative solution for this problem.
I would like to what exactly want, for instance I got a candidate record
from my query:RVCES(I implement a 5 gram index)
MSAQLRKPTA*RVCES*CGRAEHWDDDLEAWQIARTDGTKQVGSPHCLHEWDINGNFNPVAMDD
But what I want to search is RVCESCG which is 7 characters
MSAQLRKPTA*RVCESCG*RAEHWDDDLEAWQIARTDGTKQVGSPHCLHEWDINGNFNPVAMDD
one solution is that if the solr can provides the offset of the R, I could
compare the next 7 characters with my query.It will be very fast and I can
do the highlight myself.
Another solution is to compare the field with my full query using some match
functions with regular expression.
It should be low efficiency and might not provide the offset position.
Do you any guys have suggestion for this? Thanks!
