Abstract

We have developed a distributed search engine, called Cooperative Search Engine (CSE), in order to retrieve fresh information. In CSE, a local search engine located in each Web server makes an index of local pages. And, a Meta search server integrates these local search engines in order to realize a global search engine. In such a way, the communication delay occurs at retrieval time. So, we have developed several speedup techniques in order to realize fast retrieval. However, these techniques cannot be used for first page retrieval in "Next 10" search if the page has not been searched yet. So, we have proposed Query based Site Selection (QbSS), which is widely available in all cases. In this paper, we describe QbSS in detail and discuss its features.
