Examples of org.apache.lucene.index.RandomIndexWriter$TestPointInfoStream

org.apache.lucene.index.RandomIndexWriter
Silly class that randomizes the indexing experience. EG it may swap in a different merge policy/scheduler; may commit periodically; may or may not forceMerge in the end, may flush by doc count instead of RAM, etc.


    // Store the index in memory:
    Directory directory = newDirectory();
    // To store an index on disk, use this instead:
    //Directory directory = FSDirectory.open("/tmp/testindex");
    RandomIndexWriter iwriter = new RandomIndexWriter(random, directory, analyzer);
    iwriter.w.setInfoStream(VERBOSE ? System.out : null);
    Document doc = new Document();
    String text = "This is the text to be indexed.";
    doc.add(newField("fieldname", text, Field.Store.YES,
        Field.Index.ANALYZED));
    iwriter.addDocument(doc);
    iwriter.close();
    
    // Now search the index:
    IndexSearcher isearcher = new IndexSearcher(directory, true); // read-only=true
    // Parse a simple query that searches for "text":
    QueryParser parser = new QueryParser(TEST_VERSION_CURRENT, "fieldname", analyzer);
