When stored in the db, your query has full control over what is
returned and how it is returned. The pre-defined parameters, which are
valid for queries passed in the URL, are thus not applied for stored
queries. To limit the number of nodes returned, you can use an XQuery
construct like this:

let $results :=3D result-of-the-main-query
let $count :=3D count($results),
let $end :=3D if($count >=3D $max) then $max else $count
return
   subsequence($results, 1, $end)

To retrieve the result set in multiple chunks, store $results into the
HTTP session and read the following chunks from there.
