[jira] [Updated] (SOLR-9786) Defer creation of clauses in parser,
optionally delegate groups to FieldType.getSetQuery

Draft patch attached.
I also plan on doing some benchmarking of query parsing to ensure we're not slowing anything down too much.

> Solr's query parser currently creates a query for each clause it sees independently. This is no longer desirable, since if we are creating a filter (non-scoring query), we can use a TermsQuery.
> PointFields SOLR-8396 also need to see a set of values together to efficiently create a set query.
> This issue:
> - adds context for the parser to know when it's parsing a query for matching only (that's only for the TermsQuery... I assume Points would always use a set query when passed multiple values)
> - defers creation of real Query objects for simple term queries in a boolean query
> - aggregates those values by field at the end to be passed to a new FieldType.getSetQuery method
> - FieldType.getSetQuery base implementation uses TermsQuery for indexed fields
