-------------------------------------------
Summary: DBQ should use a Occur.FILTER instead of Occur.MUST
Key: SOLR-10179
URL: https://issues.apache.org/jira/browse/SOLR-10179
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Ishan Chattopadhyaya
Priority: Minor
In DUH2's getQuery() method, which is used to generate a BooleanQuery for the
DBQ operations, the main deletion clause uses Occur.MUST. Since this query
doesn't need any scoring, this clause is ultimately re-written to a
Occur.FILTER (at BooleanQuery's rewriteNoScoring()). We can avoid this query
rewrite if we use Occur.FILTER instead of Occur.MUST in the first place.
