Implement a feature that see the detail of the process for index recreation
We know that it is possible to see whether index recreation is succeeded or not with the crawl log when the search result returns which not expected.
However, the log doesn’t show the complete details such as error status of the indexing process or consumed time throughout the process and so on, by tracking the indexing progress.
We strongly ask you to implement a feature that can see the detail of the process for index recreation so that we are able to use the information for troubleshooting to address issues encountered when we had an unexpected result by search.
Because you don't know the status of reindexing, you can't avoid having to use it many times
The current logs do not indicate that the index has been created. Even the settings such as the "language neutral tokenization" in the official information can not be confirmed that it is not working. There is no way to track the managed property index status.
