make sure you fix the clippy warning.

this still works for searches containing special characters like & and spaces, correct?

Changed as suggested by clippy.

Searching for special characters has never worked correctly because komga doesn't do url decoding on the search response. That's why non-English searches didn't work before, because aidoku encodes the url and komga doesn't decode the url accordingly. This is a limitation of komga.

Any more problems here?
