Search not working in Thunderbird
Problem
You are trying to use the search function in Thunderbird, but it doesn't do anything.
Cause
This is probably due to crash in Thunderbird and it may have corrupted the search database.
Solution
Rebuild Thunderbird's Search Database by following the instructions provided in:
https://support.mozilla.org/en-US/kb/rebuilding-global-database
This process will take some time, so the Search function will not be 100% usable as it is rebuilding the database. Please give it half an hour to an hour, depending on how big your mailbox is, to rebuild the search function.
