Xapian devel - Oct 2012 - Auto completion using xapian

Hello,

Do xapian has analyzer like EdgeNGram to use it for autocomplete.

I am trying to use the auto completion using xapian.
For example:
e
ex
exa
exam
example
etc..
so that we can get it.
I tried to use using the Partial flag but it dose not work Xapian::Query
query = parser.parse_query("m*",parser.FLAG_PARTIAL);
Do you have any example or any tutorial is appreciated.

--Naveen.

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.
