What happens if you change your query string to:
String query = "quiewId:a3d32ce0cae0da47677f30cc6182d421 HTTP" ;
(adding space http)??
Does this return any hits?

Hi all, I developed a couple of plugins to add and search a custom
field.
The indexing plugin works fine (with Luke I can see the field is
added to
the index). But when it comes to search no documents are returned...
Here the plugins code:
----------------- Indexing plugin ---------------------------
package org.apache.nutch.indexer.quiew;
import ...;
public class QuiewIndexingFilter implements IndexingFilter {
public Document filter(Document doc, Parse parse, FetcherOutput fo)
throws IndexingException {
String url = fo.getUrl().toString();
doc.add(new Field("quiewId", MD5Hash.digest(url).toString(),
true, true,
false));
return doc;
}
}
---------------- Query plugin ----------------------
package org.apache.nutch.searcher.quiew;
import org.apache.nutch.searcher.FieldQueryFilter;
public class QuiewQueryFilter extends FieldQueryFilter {
public QuiewQueryFilter() {
super("quiewId");
}
}
And here's how I try to perform the query:
String query = "quiewId:a3d32ce0cae0da47677f30cc6182d421";
NutchBean bean = new NutchBean(new File(indexPath));
Query q = Query.parse(query);
Hits hits = bean.search(q, 1000);
long tot = hits.getTotal();
System.out.println("Query returned " + tot + " hits.");
for(int i = 0; i < tot; i++) {
Hit hit = hits.getHit(i);
HitDetails details = bean.getDetails(hit);
System.out.println("Resource title: " + details.getValue("title"));
System.out.println("Resource url: " + details.getValue("url"));
}
If I perform the same query with Luke, I get correct results, but
only if I
use the KeywordAnalyzer...
What am I doing wrong?
Thanks,
Enrico
