OK, let me plan for the Simple Lucene:

0. Parse all HTML fields into Text fields; [24:00, 26 Nov]
1. Add all public notes to a Index with public attribute, all private notes with private attribute; [1:00am, 27 Nov]
2. Make a query and a result page using HttpServlet; [10:00, 27 Nov]
3. Pin the search button on the left corner of the whizznotes pages; [11:00, 27 Nov]
4. Study the Analyzer for Chinese;
5. Incremental Indexing; [13:00, 27 Nov]
