Uwe Schindler commented on SOLR-4940:
-------------------------------------
see SOLR-1726
The main issue is: full-text search engine are only good in returning
"top-ranking" results. If you increase the window of top-ranking results the
underlying algortithms, which are optimized to do the "find top-n fast", will
need lots of memeory and get slow.
> Cluster crashed for *:* queries with large page number (OOM)
