hi folks,
i have great trouble while using lucene to implement search functionality to
my application:
this way i index:
[code]
public void indexData() throws CorruptIndexException,
LockObtainFailedException, IOException {
Analyzer analyzer = new StandardAnalyzer();
IndexWriter iwriter = new IndexWriter(indexFolder, analyzer,
true);
iwriter.setMaxFieldLength(25000);
Document doc = new Document();
for (int i = 0; i < sourcefiles.size(); i++) {
for (int j = 0; j <
sourcefiles.elementAt(i).getNumberOfRevisions(); j++)
{
doc.add(new Field("id",
sourcefiles.elementAt(i).getID(j),
Field.Store.YES, Field.Index.UN_TOKENIZED));
doc.add(new Field("message",
sourcefiles.elementAt(i).getCommitMessage(j), Field.Store.NO,
Field.Index.TOKENIZED));
iwriter.addDocument(doc);
System.out.println("Indexed: Source: " + (i+1)
+ " Revision: " +
(j+1));
System.out.println(sourcefiles.elementAt(i).getCommitMessage(j));
System.out.println(sourcefiles.elementAt(i).getID(j));
}
}
iwriter.optimize();
iwriter.close();
}
[/code]
and this way i make the query
[code]
public void luceneSearch(String queryString) throws CorruptIndexException,
IOException, ParseException {
System.out.println("Searching started");
IndexSearcher isearcher = new IndexSearcher(indexFolder);
Analyzer analyzer = new StandardAnalyzer();
QueryParser parser = new QueryParser("message", analyzer);
org.apache.lucene.search.Query query =
parser.parse(queryString);
Hits hits = isearcher.search(query);
if(hits.length() > 0) {
System.out.println("found: " + hits.length() + "
documents.");
for (int i = 0; i < hits.length(); i++) {
System.out.println((i + 1) + ". " +
hits.doc(i).get("id") +
hits.doc(i).getField("message"));
}
} else {
System.out.println("No matching documents found.");
}
}
[/code]
my problem is, that the query always returns a lot of too much results. and
the other problem is, the id is always for every result in the list the same
id, namly the first i added to the writer. and the message is always null.
while adding i check with sysout that all the ids are different and the
messages arent null
whats going wrong?? thx for your hints
