NSX 3.2.x
If OpenSearch is overloaded and unable to process data efficiently, index refreshes may fail. In these cases, objects within the affected indexing batch should be considered as failed, as they will not be retrievable through search queries.
This issue is resolved in VMware NSX 4.2.0
Workaround:
Issue the non-impactful command "start search resync all" on all NSX managers
