When the index is generated with a more recent Haddock, you get a search field, which does an incremental search, so this might perhaps be more what you are looking for. A more aesthetical note: We should really get rid of the ugly table/CSS layout mixture, the lower part of the page renders a bit ugly and varies between browsers. Switching to pure CSS should be safe in 2007, I guess.
Please, please, someone do this for me. I tried, and failed, to get the layout right for the contents list in all browsers at the same time. The semantics of CSS is beyond my comprehension.
Well, I'm not a web designer, but I did work with few of them, and it seems to me that you either create a table design in two hours or spend three days trying to create a CSS one and THEN create a table design in two hours.
