However, the disadvantage of this approach is that if one is looking for more specific information, such as on "steroids" or "penicillin," one may not find these among the categories and subcategories of the directory, so the data one is looking for may remain hidden among the millions of web pages. Hence Yahoo! began working with Inktomi, developers of "full-text" search tools.
不過這種方式的缺點是，如果網友要尋找更細的資料，例如「類固醇」、「盤尼西林」等，在分類網站目錄可能就找不到，這樣的資料可能埋藏在數百萬頁的網頁中，於是雅虎又和發展「全文檢索」功能的 Inktomi 公司合作。
