Wildcard search doesn't work

(from github.com/maze13)
The wildcard search doesn’t work. When I search for test many documents with test inside are found. When I search for t?st or t*st no documents are found.

I am using fess 13.4.2.

It works correctly.
If we look into this issue, could you provide steps to reproduce it?
