I am closing the directory and that's the line where the exception about the
open files is being thrown:
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));
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. If I leave this in I
get an error about the files being open
}
}
Interestingly, if I change the *** line above to use the deprecated constructor
taking just the directory it works fine:
IndexSearcher searcher = new IndexSearcher(directory);
