I was using lucene 3.6 and my function worked well. After I changed the
version of lucene to 4.0 and did some adjustments and my function is not
working. Someone tell me what do you know I'm doing wrong?
public List <String> fuzzyLuceneList(List<String> list, String s) throws
CorruptIndexException, LockObtainFailedException, IOException,
ParseException {
List<String> listr = new ArrayList<String>();
Analyzer analyzer = new StandardAnalyzer(Version.LUCENE_40);
Directory directory = new RAMDirectory();
IndexWriterConfig config = new IndexWriterConfig(Version.LUCENE_40,
analyzer);
IndexWriter iwriter = new IndexWriter(directory, config);
Document doc;
for (int i = 0; i < list.size(); i++) {
doc = new Document();
doc.add(new Field("fieldname", list.get(i), Field.Store.YES,
Field.Index.ANALYZED));
iwriter.addDocument(doc);
}
iwriter.close();
IndexReader reader = IndexReader.open(directory);
IndexSearcher isearcher = new IndexSearcher(reader);
Term term = new Term("fieldname", s);
Query query = new FuzzyQuery(term, 1,0);// 0-2
TopScoreDocCollector collector = TopScoreDocCollector.create(10,
true);
isearcher.search(query, collector);
ScoreDoc[] hits = collector.topDocs().scoreDocs;
for (int i = 0; i < hits.length; i++) {
Document hitDoc = isearcher.doc(hits[i].doc);
listr.add(hitDoc.get("fieldname"));
}
//isearcher.close();
directory.close();
return listr;
}
Thanks!
