Not get result using index after Data Node OOM

Hi all,

I did not get query result using index after data node OOM killer. my couchbase use AWS EC2 and Couchbase Enterprise 4.6.3.

Couchbase Cluster has 7 data&query node and 4 index node, but one of the them was restarted due to OOM Killer. and then Query result is always 0 although bucket has a lot of data.

In general, when the data node is restarted, can the result of the index not be all?

If query returns 0 means indexer might not have returned any items. Checkout which index query using and how many items it has indexed.
