Yonik Seeley updated SOLR-998:
------------------------------
Attachment: SOLR-998.patch
In addition to fixing the FileFloatSource failure by allowing an individual
segment to use the cache based on the entire multireader, this patch lays the
groundwork for caching per-segment reader.
The basic idea is that IndexReaders are wrapped by SolrIndexReaders each time a
new IndexSearcher is opened - thus allowing any segment reader to know what
multireader it is a part of... and the SolrIndexReader wrapper provides a
better platform for caching than using weak references on IndexReaders.
I'll commit shortly - comments welcome.

> reopen() causes segments to be reused, and new segment-at-a-time searching in
> Lucene causes FileFloatSource to be reloaded per-segment (and thus get a hit
> on the old segments). Per-segment loading of FileFloat Source is very
> inefficient in any case.
