Hello, We have two solr searchers/instances (read-only). They read the same index, but they did not return the same #hits for a particular query
Log is below, but to summarize: first server always returns 576 hits, the second server returns: 440, 440, 576, 576... These are just few seconds apart. Load balancer directed requests to both servers. Both servers report the same numHits for other queries. I checked that nothing re-opened index, there was no error....this is SOLR 4.0 (we should update, I know), running CentOS, the index lives on a RAID5 mounted volume, both instances just read it (the index wasn't updated while these searches happened). Anybody has a pointer, I can't really understand it. Can it be a bug? Thanks, roman If you look at the log below, you will see 9002 instance always returns 576 hits, but 9003 instance is returning 440, 440, 65, 576 -bash-4.1$ grep -a -e
