Based on these events, we decided to rebuild index for these two troubled DBs. After reindexing, everything goes to normal and users can do search from their mailbox again.

 

Here is list of cmdlet I used for reindex. (note: please plan run the cmdlet off hours since it uses CPU resources)

 

1. GetSearchIndexForDatabase -All

    to get list of index folder of all DBs. You will notice that these two troubled index folder's last modified date is not current.

 

2. ResetSearchIndex.ps1 -force  DB1

    ResetSearchIndex.ps1 -force  DB2

 

Note: it only needs DB name. it doesn't asked for Storage Group name or server name.
