Hi All, ``` I have an index with 51 millions records i have 2 nodes in my ``` cluster. ``` no of shards for the above index is : 5 replicas are :1 my question is how many records we can index to get better ``` search capabilities? Is there any limitation for the index that will hold these many records. or please suggest me what are the settings in elasticsearch.yml file to optimize the index which is hoding 51 million records. ``` can we increase number of shards other than five ? if we ``` increase that one is there any problems with searching records? ``` please help me. ``` Thanks phani -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Depends on your setup. Increasing shard count is only going to be useful if you add more nodes.
