Hi David, Thanks so much for your reply. hl.weightMatches was indeed the culprit. After setting it to false, I am now getting the same sub-second response as Solr 6. I am using Solr 8.6.1 (<luceneMatchVersion>8.6.1</luceneMatchVersion>)
Here are the tests I carried out: hl.requireFieldMatch=true&hl.weightMatches=true (2458 ms) hl.requireFieldMatch=false&hl.weightMatches=true (3964 ms) hl.requireFieldMatch=true&hl.weightMatches=false (158 ms) hl.requireFieldMatch=false&hl.weightMatches=false (169 ms) (CHOSEN since this is consistent with our earlier setting). Thanks again, I will inform our other teams as well doing the Solr upgrade to check the CHANGES.txt doc related to this.
