[Xapian-devel] Auto completion using xapian

[James Aylett]

A query string such as "m*" is using the wildcard expansion operator – if you want to use the partial support, you don't want the * at the end of your query string.

It's also not clear from your message whether you've set a database before trying to parse your query. You need to do this, because Xapian's wildcard support (which is what partial uses) is done at query time, expanding to all the possibly matching terms, rather than at index time in an n-gram analyzer style.

If you still can't get this to work, try posting a complete program rather than just a snippet.
