[Exist-open] Lucene index ft:query function not found

[ashok _ <lis...@gm...>]

Hi,

I am running eXist 1.4 (built from source from svn) --

I have enabled lucene indexing via collection.xconf [1]

I have an Xquery which declares the ft namespace like this :

declare namespace ft = "http://exist-db.org/xquery/lucene" ;

and then further down i query the fulltext index :

for $result in collection($data-collection)//*[ft:query(., $q)]
   return
           <p>{data($results)}</p>

Unfortunately i keep getting the error on the above line :

Call to undeclared function: ft:query

What am i missing ?

thanks in advance,

Ashok
