Description

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
