Hi,
I'm trying to brush up on some of the *cough* newer APIs (we've been using
2.9.2 up until now). Anyway, I have the test below which a modified version of
one of the tests in Lucene In Action, but uses LuceneTestCase as a base class.
public class MetaphoneReplacementAnaylyzerTest extends LuceneTestCase {
@Test
public void testKoolKat() throws Exception {
Analyzer analyzer = new MetaphoneReplacementAnalyzer();
IndexWriterConfig config = new
IndexWriterConfig(Version.LUCENE_36, analyzer);
// Directory directory = new RAMDirectory();
Directory directory = newDirectory();
IndexWriter writer = new IndexWriter(directory, config);
Document doc = new Document();
doc.add(new Field("contents", "cool cat", Field.Store.YES,
Field.Index.ANALYZED));
writer.addDocument(doc, analyzer);
writer.commit();
IndexSearcher searcher = new
IndexSearcher(IndexReader.open(directory));
// IndexSearcher searcher = new
IndexSearcher(IndexReader.open(writer, true));
Query q = new QueryParser(Version.LUCENE_36, "contents",
analyzer).parse("kool kat");
TopDocs hits = searcher.search(q, 1);
assertEquals(1, hits.totalHits);
int docID = hits.scoreDocs[0].doc;
doc = searcher.doc(docID);
assertEquals("cool cat", doc.get("contents"));
writer.close();
searcher.close();
directory.close(); // if I comment this out, I get an assertion
failure about the directory not being closed
}
}
My issue is that I get the following stack trace when I try to close the
directory. I've tried variations of closing the writer instead of calling
commit etc, but I think I'm just missing something fundamental here. Note that
obviously if I change :
Directory directory = newDirectory();
to:
Directory directory = new RAMDirectory()
everything works, but I'd love to know how to correctly close the writer,
searcher etc.

Any insight would be greatly appreciated.
