Thank you very much, now I know where I am going...
Hope I am not bothering you...
So I am still having problems... Should I implements the QueryFilter interface
to get this plugin working?
Here is my code:
public class PersoSearch implements QueryFilter{
{
try {
Query query = new Query();
query.addRequiredTerm("foobar");
// Create a Configuration for Nutch. Configuration Provides access to
configuration parameters.
Configuration conf = NutchConfiguration.create();
// Path to crawled index folder
Path path = new Path("C:\\cygwin\\nutch-0.8.1\\crawled\\index");
IndexSearcher searcher = new IndexSearcher(path , conf);
NutchBean nutchBean = new NutchBean(conf);
Hits hits = nutchBean.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();
}
}
public BooleanQuery filter(Query input, BooleanQuery translation) throws
QueryException {
// TODO Auto-generated method stub
return null;
}
public void setConf(Configuration arg0) {
// TODO Auto-generated method stub
}
public Configuration getConf() {
// TODO Auto-generated method stub
return null;
}
}
But it is stille not working, I have the following messages:
2006-10-11 12:58:06,238 WARN QueryFilters - QueryFilter: PersoSearch names no
fields.
2006-10-11 12:59:11,534 INFO NutchBean - query request from 127.0.0.1
**2006-10-11 12:59:11,534 INFO NutchBean - query:

2006-10-11 12:59:11,550 INFO NutchBean - searching for 20 raw hits
**As you can see, the query is empty...
And if it is not asking too much, can you plz explain the concept of "field"?
What's the difference between a field and a term?
Thanks a lot again!

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.

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();
