Search is not working properly on cluster 2 node setup

Hi Elastic team,

I am using Elasticsearch service on 2 node setup. Both the nodes have default configuration (elasticsearch.yml).

Case : Suppose there are 50 entries in a list to search from. A new entry ("newentry51") is added in the list making the total count of entries = 51. After restarting both the nodes, if I try to search "newentry51", then "newentry51" will come in results only on every alternate occasion i.e. (1st time search - getting "newentry51" in results, 2nd time search - not getting, 3rd time search - getting, and so on...).

Please suggest if there is any configuration to automatically refresh search index after rebooting the nodes or if there is any approach to solve this problem.

*This problem is happening after VM reboot

Thanks.

Welcome to our community! :smiley:

Please share an example that we can use to replicate this, eg documents and mappings, your search request etc.

Please check the description, I have shared configurations and some extra details in the end. Also there is an example in the description given to follow.
