After the site re-design, we have implemented (if you do not already noticed it) a search page, accessed through a link at the left of the top navigation toolbar.
We have also developed a completely new search engine located at: /Sections/Search/DetailedSearch1.aspx
This is in beta right now and the final version will be similar to what you see know, with some cosmetic improvements. (The existing colors are being used mainly for distinguishing logically the various layout parts.)
Please submit any found bugs here for helping us to improve it.
