Usage

From source file:com.bizosys.hsearch.index.IndexReaderTest.java

private void tryOut() throws Exception {
    Scanner in = new Scanner(System.in);
    String query = in.nextLine();
    in.close();

    QueryContext ctx = new QueryContext(acc, query);

    QueryResult results = null;//from   www .j av  a 2s. com
    results = IndexReader.getInstance().search(ctx);

    int size = (null == results) ? 0 : (null == results.teasers) ? 0 : results.teasers.length;
    if (0 == size) {
        System.out.println("<list></list>");
        return;
    }

    System.out.println(results.toString());
    System.out.println(IndexReader.getInstance().get(acc.name, "6EY-VF9U5uQ"));
