Hi Tim,
Thanks for the hint, I have updated the documentation. The computed error value is 0 if a token has 0 to 3 characters.
All the best,
Christian

Hello,
I am trying to match a local dataset against entries in a full-text index. I ran into the following case and was confused about the fuzzy querying performance:
<x>Baxter, Richard, 1615-1691</x>[text() contains text "Baxter, Richard, 615-1691" using fuzzy]
The BaseX documentation says that the default fuzzy search will preserve a minimum of 1 error. However, the query above returns no result. If I add the "errors" parameter with a value of 1, it does work:
<x>Baxter, Richard, 1615-1691</x>[text() contains text "Baxter, Richard, 615-1691" using fuzzy 1 errors]
Is this expected behavior?
Thanks in advance,
Tim
