Hi, Remember the friendly "explore concepts" view that gets displayed on yahoo's search page. I'm talking about the small arrow below the search box on the search.yahoo.com page that opens into a dark blue frame containing related keywords and categories to narrow down your search. I'm wondering if yahoo's web search API supports this feature. I know that related keywords can be obtained thru the web search API and the categories can be listed thru local search API. But, is there a way I can see the related concepts/categories for a search string using the web search API? Pls advice! Thanks.
