Solr proximity search highlighting issue

[Nirav Shah <ns...@knovos.com>]

Hello Dev Team,

I found some problem in highlighting module. Not all the search terms are getting highlighted.

Sample query: q={!complexphrase+inOrder=true}"pos1 (pos2 OR pos3)"~30&hl=true
Indexed text: "pos1 pos2 pos3 pos4"

please find attached response xml screen shot from solr.

You can see that only two terms are highlighted like, "<em>pos1</em> <em>pos2</em> pos3 pos4"

The scenario is same in Solr source code since long time (I have checked in Solr version 4 to version 7). The scenario is when term positions are in-order in document and query both.

Please let me know your view on this.

Thank you,
Amit
