Re: [basex-talk] string:levenshtein producing incorrect results?

[Christian Grün]

Hi Hack,

That’s been helpful, thanks. We’ve aligned our Damerau/Levenshtein

Christian

Re: [basex-talk] BaseX installation cannot see Java

[Christian Grün]

Thanks for the insight. We’ll need to ensure that the check runs with all
