Starting in the Domino 4.6 server, there is the ability to open a view and have the browser go directly to a specific document or category. To do this, there is a new parameter which needs to go on the end of the URL called &StartKey. For example, if you have a view where the first column is sorted by subject, you can go to the document with a subject of "Tip Of The Day" by opening the view with a URL like:

http://<server>/<database>/<view>?OpenView&StartKey=Tip+Of+The+Day

You have to make sure that the first column in the view is sorted. Basically, this works the same as being in the Notes client and typing in text for the "fast search". Whatever you can type in that client interface will work in the same view in the browser.
