If I want to get all new posts since my last visit, there is the New Posts on the right hand pane. If I want to look for a specific word in specific forums in posts since my last visit I can used the Search/Advanced Search function.

However, I cannot find all new posts since my last visit in specific forums because the Advanced Search requires a word in the search term and it doesn't allow words like "the".

Would it be possible to allow Advanced Search to be run without a search term?
