Overview
In Advanced Vault Settings, 7z is listed as excluded when choosing the 'Use File Extension Blacklist Instead of Whitelist in Indexing' option and setting it to 'Yes'.
However, even if choosing 'No', 7z is still not indexed. This is by design as 7z containers are not supported by our 3rd party extraction software.
Solution
If file contents need to be indexed, using Zip format instead of 7z is advised.
