@ashvardanian Thank you for updating to the new version, everything is ok.
But I want to ask more about how I want to get the "cosine distance" after searching, currently the default is only [keys]
It's difficult without a "distance" result.

@ThangTo, sure, we can change the Java interface to be more similar to other bindings. Any chance you or @superkelvint could contribute? Thank you!

@ashvardanian That is currently beyond my ability, I am having difficulty coding C/C++(never coded C/C++ before), can you help me. Haizz
Maybe we need to wait for someone to contribute
