Hi, I did some testing of several search words with 1 node, 1 index with 5 shards and no replicas. Later I set 1 replica for the index, activated a new node with same cluster name on another machine, the node identified the master and created the replicas. I ran the same text search as before, this time 2 nodes running, and I got a smaller amount of hits for the same search text. I also tried running only node 1, and also only node 2, but I still get the same missing results.

Double check that the primaries still have the number you thought they did. It could be that something changed in your index and you perhaps forgot? Even better, check that the primaries and replicas have the same number of docs. An easy way to check is with `es shards -v` using the [GitHub - elastic/es2unix: Command-line ES](https://github.com/elasticsearch/es2unix) utility. The doc counts for each shard's `p' and `r' should match. -Drew -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

When I shut down node 2 that has the replicas and work only with node 1 with the primaries, I still get smaller amount of hits than before I activated the replica for the index. Doesn't it mean that the problem is not about different number of docs in primaries and replicas?

Hey Ophir, can you maybe give some more information about what is going on? are you doing a search and the number of returned hits is less than before or do you look at the number of documents in the index? simon On Tuesday, February 19, 2013 10:36:08 AM UTC+1, Ophir Michaeli wrote: > When I shut down node 2 that has the replicas and work only with node 1 > with the primaries, > > I still get smaller amount of hits than before I activated the replica for > the index. > > Doesn't it mean that the problem is not about different number of docs in > primaries and replicas? > > Thanks, Ophir > > On Monday, February 18, 2013 8:38:56 PM UTC+2, Drew Raines wrote: > > > Ophir Michaeli wrote: > > > > > Later I set 1 replica for the index, activated a new node with same > > > cluster name on another machine, the node identified the master and > > > created the replicas. > > > > > > I ran the same text search as before, this time 2 nodes running, > > > and I got a smaller amount of hits for the same search text. > > > > Double check that the primaries still have the number you thought > > they did.

Yes, I'm doing search and the number of returned hits is less than before setting 1 replica and opening another node.
