Enrico,
What does your plugin.xml file look like? Also, what happens if
you do a search for:
quiewId:a3d32ce0cae0da47677f30cc6182d421

Quite interesting (I think), if I use lucene api to perform the query I
get
exactly what I'm expecting...
Searcher searcher = new IndexSearcher(indexDir);
Analyzer analyzer = new NutchDocumentAnalyzer();
Query query = QueryParser.parse("a3d32ce0cae0da47677f30cc6182d421",
"quiewId", analyzer);
System.out.println(query);
System.out.println("Searching for: " + query.toString("quiewId"));
Hits hits = searcher.search(query);
System.out.println(hits.length() + " total matching documents");
Do you have any suggestion?
Thanks,
Enrico
