http://www.w3.org/TR/xpath-full-text-10-use-cases/#xquery-xpath-composability-queries-results-q9 current solution is for $book in doc("http://bstore1.example.com/full-text.xml") /books/book for $cont := $book/content[. ftcontains ("successfully" ftand "completing" ftand "tasks") with stemming window (count(./contents/part/chapter) * 3) words] where count($cont)>0 return ($book/metadata/title, $cont) the correct solution is for $book in doc("http://bstore1.example.com/full-text.xml") /books/book let $cont := $book/content[. ftcontains ("successfully" ftand "completing" ftand "tasks") with stemming window (count(./part/chapter) * 3) words] where count($cont)>0 return ($book/metadata/title, $cont) second 'for clause' shall be 'let clause'. ./contents path shall be eliminated because there is NO contents element.
Zhen, I handled these as editorial. I changed the 2nd for clause to a let in the XQuery solution. I fixed the ./contents/part/chapter paths in bothe XQuery and XPath solutions. The correction will appear internally after the next use cases build. I will send the FTTF an alert when it is ready. Please review and if you agree with the change, close the bug. Pat
