thank you guys.I debuged search.jsp,It seems nutch can recognize the sentence that I input.I' m little confused about how does Nutch parse a query string,and dertermine what fields it will search in.I used luke to check the indexes,It seems fine.I can get search result.buy the way I changed the tokenstream funciton in NutchDocumentAnalyzer.java,to use a chinese analyzer.I have been debugging the whole day,still have no clue.
