> -----------------------------------------------------

> Key: LUCENE-5040
> URL: https://issues.apache.org/jira/browse/LUCENE-5040
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/codecs
> Affects Versions: 4.3
> Environment: any
> Reporter: Adrian Nistor
> Priority: Minor
> Labels: patch, perfomance

> The problem appears in version 4.3.0 and in revision 1490286. I
> attached a two-line patch that fixes it.
> In method "Lucene40TermVectorsWriter.finishTerm", the loop over
> "offsetStartBuffer" should not be executed when "offsets" is "false".
> When "offsets" is "false" the loop produces no results. The patch
> just flips the order of the "if" and "for" statements.
> Method "collect" in class "MultiComparatorNonScoringCollector" has a
> similar loop (the last loop in the method over "comparators"), and
> this loop is not executed when "queueFull" is false, just like in the
> proposed patch.
