-------------------------------------
Summary: The order of disjuncts in DisjunctionMaxQuery affects
equals() impl
Key: LUCENE-9940
URL: https://issues.apache.org/jira/browse/LUCENE-9940
Project: Lucene - Core
Issue Type: Bug
Reporter: Alan Woodward
Assignee: Alan Woodward
DisjunctionMaxQuery stores its disjuncts in a java array, and its equals()
implementation uses Arrays.equal() when checking equality. This means that two
queries with the same disjuncts but added in a different order will compare as
different, even though their results will be identical. We should replace the
array with a Set.
