Clinton Gormley created LUCENE-5784:
---------------------------------------
Summary: CommonTermsQuery HighFreq MUST not applied if lowFreq
terms
Key: LUCENE-5784
URL: https://issues.apache.org/jira/browse/LUCENE-5784
Project: Lucene - Core
Issue Type: Bug
Components: core/query/scoring
Affects Versions: 4.8.1
Reporter: Clinton Gormley
Priority: Minor
Attachments: common_terms.patch
When a CommonTermsQuery has high and low frequency terms, the highFreq terms
Boolean query is always added as a SHOULD clause, even if highFreqOccur is set
to MUST:
new CommonTermsQuery(Occur.MUST, Occur.MUST,0.1);
My patch sets the top level Boolean query's minimum should match to 1 to ensure
that the SHOULD clause must match. Not sure if this is the correct approach,
or if it should just add the highFreq query as a MUST clause instead?
