        public virtual void TestDemo()
        {
            Analyzer analyzer = new MockAnalyzer(random());

            // Store the index in memory:
            Directory directory = newDirectory();
            // To store an index on disk, use this instead:
            // Directory directory = FSDirectory.open(new File("/tmp/testindex"));
            RandomIndexWriter iwriter = new RandomIndexWriter(random(), directory, analyzer);
            Document doc = new Document();
            string longTerm = "longtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongtermlongterm";
            string text = "this is the text to be indexed. " + longTerm;

            iwriter.addDocument(doc);
            iwriter.close();

            // Now search the index:
            IndexReader ireader = DirectoryReader.open(directory); // read-only=true
            IndexSearcher isearcher = newSearcher(ireader);

            Assert.AreEqual(1, isearcher.search(new TermQuery(new Term("fieldname", longTerm)), 1).totalHits);

            TopDocs hits = isearcher.search(query, null, 1);
            Assert.AreEqual(1, hits.totalHits);
            // Iterate through the results:
            for (int i = 0; i < hits.scoreDocs.length; i++)
            {
              Document hitDoc = isearcher.doc(hits.scoreDocs[i].doc);
