What characters are valid in couchdb-lucene keys?

I can store values ​​in couchdb-lucene with any keyword that I like, but it seems that if the key contains any characters outside of [0-9a-zA-Z_], no search is performed.

Does anyone know which characters are valid and / or how to avoid special characters in searches so that special characters can be used?

All UTF-8 characters should work. I just checked that I can search for elements with é, for example.

A little more information about how you request will help, although given the age of this ticket, you may have moved.
