Re: Accessing term frequency with/without Vector?

[Erik J]

Hello,

Thanks for the input, I tried the following:
public void handleFreq(String searchstring){
  NutchBean bean = new NutchBean();
  Query query = Query.parse(searchstring);
  Hits hits = bean.search(query, 100);

  for(int i = 0; i < hits.getLength(); i++) {
     Hit hit = hits.getHit(i);
     int docno = hit.getIndexDocNo();
     FSDirectory dir = 
FSDirectory.getDirectory("C:/nutch-0.7.2/results/crawl/index", false);
     IndexReader reader = IndexReader.open(dir);

     TermDocs td = reader.termDocs(new Term("contents", searchstring));
     int freq=0;
     while (td.next()) {
        System.out.println("Inside while-loop");
        if (td.doc() == docno) {
           freq = td.freq();
           System.out.println("Document no: " + td.doc());
           System.out.println("Term frequency: " + freq);
        }
     }
  }
}

The problem is that "td" seems to be empty since the while-loop is never 
entered. I suspect it might be the rows starting with "TermDocs td "or 
"FSDirectory " that are causing the problems.

I would very much appreciate any help since I am completely stuck!

Best regards,

Erik
