>                 Key: SOLR-669
>                 URL:
>             Project: Solr
>          Issue Type: Improvement
>    Affects Versions: 1.3
>            Reporter: Fuad Efendi
>   Original Estimate: 1,680h
>  Remaining Estimate: 1,680h
> It is huge performance bottleneck and it describes huge difference between qtime and
SolrJ's elapsedTime. I quickly browsed SolrIndexSearcher: it caches only (Key, DocSet/DocList
<Lucene Ids>) key-value pairs and it does not have cache for (Query, FacetFieldList).
> filterCache stores DocList for each 'filter' and is used for constant recalculations...
> This would be significant performance improvement.
