Subsearch doesn't work after upgrade to 4.3.6

[lqiao]

Hi,

I have a search as follows:
query 1 [search query 2]

I find in the internet that Searches that contain subsearches do not return data in environments where search heads are running version 5.0.x and indexers are running version 4.3.x. To work around this issue, upgrade indexers to the same version as the search heads. (SPL-62457).

But our indexers are running version 4.3.5.2 and we upgraded search head to 4.3.6. Then the above search doesn't return any data any more. It works fine with search-head 4.3.5.2.

My problem is the same as known issue SPL-62457? If I upgrade indexer also to 4.3.6, this problem will disappear?

Thank you very much for your kink answer.

I found an answer to my own question. This problem is a known issue for release 4.3.6. See below:

•Searches that contain subsearches do not return data in environments where search heads are running version 4.3.6 and indexers are running prior to 4.3.6. To work around this issue, upgrade indexers to the same version as the search heads. (SPL-65120)
