> 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
> Assignee: Simon Willnauer
> 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?
