[basex-talk] Query question

Dear All,

Is it possible to formulate a query which gives the distinct documents from a repository containing a specific word:

let $range := 1 to 640 for $doc in collection('brievenvangogh') let $uri := base-uri($doc), $num := substring($uri, string-length($uri) - 6, 3) where $num castable as xs:integer and xs:integer($num) = $range return <document uri='{$uri}'>{ for $n score $s in $doc//*[text() contains text 'cezanne'] return <hit score='{$s}'>{ $n }</hit> }</document>

In this query I get the number of hits of all documents in the repository.

Thanks in advance!

Regards,

Wiard
