Custom Google Search is good for small sites but crap for sites with large amounts of pages (like RHP forums). People generally only use because they get a bit of revenue from all the Google Ads in the search results.
If RHP built their own search system it would be far more efficient and generate much more accurate results. However, it would be quite a big drain on database resources and would only work well if the database was well organised.
