Solr Highlighting not working

[Ajay Sharma <aj...@indiamart.com.INVALID>]

Hi Community,

This is the first time, I am implementing a solr *highlighting *feature.
I have read the concept via solr documentation
Link- https://lucene.apache.org/solr/guide/8_2/highlighting.html

To enable highlighting I just have to add *&hl=true&hl.fl=* *in our solr
query and got the snippet in the solr response and it is working fine in
most of the cases.

*But highlighting does not work when synonyms came into action*

*Issue:*
I am searching leopard (q=leopard) in field title (qf=title)

In our synonym file, we have an entry like below
*leopard,tenduaa,panther*

and in one document id:123456, field title contains below text:
title:"Jindal Panther TMT Bars

For the query (q=leopard) , i am getting this document (id:123456) in solr
response
I could check that due to synonym document is matched  and I confirmed it
via Solr UI analysis screen where I put Analyse FieldName= title,  Field
Value (Index) ="Jindal Panther TMT rebars" and Field Value (Query) =
leopard and I could see in index chain, token panther getting saved as
leopard also but in highlighting I don't get any matched token and getting
below response


   - highlighting:
   {
      - 123456: { }
      }



I just need the matched synonym token like panther in the above case to be
returned in solr highlighting response
I have read and re-read the solr documentation, searched on google gone
through many articles even checked StackOverflow but could not find a
solution.
Any help from community members will be highly appreciated.

Thanks in advance.

Hi All,

pushing the query to the top.
Does anyone have any idea about it?
