LUCENE-6639: Make LRUQueryCache consider a query as used on the first time a
Scorer is pulled.
> LRUQueryCache.CachingWrapperWeight not calling policy.onUse() if the first
> scorer is skipped
> --------------------------------------------------------------------------------------------
>
> Key: LUCENE-6639
> URL: https://issues.apache.org/jira/browse/LUCENE-6639
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 5.3
> Reporter: Terry Smith
> Priority: Minor
> Fix For: 5.3
>
> Attachments: LUCENE-6639.patch
>
>
> The method
> {{org.apache.lucene.search.LRUQueryCache.CachingWrapperWeight.scorer(LeafReaderContext)}}
> starts with
> {code}
> if (context.ord == 0) {
> policy.onUse(getQuery());
> }
> {code}
> which can result in a missed call for queries that return a null scorer for
> the first segment.
