Hi Jason Thanks for reply.
I have checked jay's query using "terms" query parser and it is really helpful to us. After execute using "terms" query parser it will come within a 500 milliseconds even though grouping is applied. Jay's Query : https://drive.google.com/file/d/1bavCqwHfJxoKHFzdOEt-mSG8N0fCHE-w/view Actually I want to apply same things in my query but my field "msg_id" is applied boost.group is also used in my query. I am also upgrading Solr 8.5.1. MY query is : https://drive.google.com/file/d/1Op_Ja292Bcnv0Ijxw6VdAxvGlfsdczmS/view I got 30 seconds for above query. How can I use the "terms" query parser in my query?

What I can suggest though is an alternative way of formulating the query: you might get different performance if you run your query using Solr's "terms" query parser: https://lucene.apache.org/solr/guide/8_5/other-parsers.html#terms-query-parser It's not guaranteed to help, but there's a chance it'll work for you. And knowing whether or not it helps might point others here towards the cause of your slowdown. Even if "terms" performs better for you, it's probably worth understanding what's going on here of course. Are all other queries running comparably?
