Hi,
We are encountering this no results issue for any index logs in only search head cluster, but we can search the logs in non-clustered search heads. Please let us know if you found this or happenned to anyone.

Does your search heads in the cluster have appropriate search peers setup?? (Settings->Distributed Search-> Search peers)
yes we do have all the peers are running fine. with both the ends.
Is it happening for just one index or all the indexes?? If it's just one index, then check whether your role has setup to search that index in the cluster.
