Re : Searching terms saved in a file

[frgrfg gfsdgffsd <ki...@yahoo.fr>]

Thanks a lot Dennis!
But it is still not that clear to me...
Have you got any example of how constructing a Query object using the addRequired and addProhibited methods? (I am also beginner in Java...)
And what doo you mean by "Then pass that into the appropriate NutchBean search method"??
Any code example?
Actually my problem is that the Nutch javadoc is not really clear to me, any better documented docs somewhere?
Thank you very much again!!
Mat

You would have to write something that would loop through the file and 
then construct a Query object using the addRequired and addProhibited 
methods to add your terms and phrases.  Then pass that into the 
appropriate NutchBean search method to get your results.

Try something like this.  The conf folder holding the nutch-site.xml and 
hadoop-site.xml file must be in the classpath here. I have the file 
system set to local and I have an index on the local filesystem.

Dennis

try {
     
      Scanner scanner = new Scanner(new File("C:\\d01\\searchterms.txt"));
      Query query = new Query();
      while (scanner.hasNext()) {
        query.addRequiredTerm(scanner.nextLine().trim());
      }
     
      Configuration conf = NutchConfiguration.create();
      IndexSearcher searcher = new IndexSearcher(new 
Path("C:\\d01\\crawl3\\index"), conf);
      NutchBean bean = new NutchBean(conf);
      Hits hits = bean.search(query, 10);
      HitDetails[] details = searcher.getDetails(hits.getHits(0, 
hits.getLength()));
     
      for (int i = 0; i < details.length; i++) {
        HitDetails curDetail = details[i];
        System.out.println(curDetail);       
      }
    }
    catch (IOException e) {
      e.printStackTrace();
    }
