With the rapid growth of the network information, how to search the relative information in the web becomes a new challenge. The algorithm of search engine is the key to search on web accurately and rapidly, and the research of search engine algorithm is still a hot issue of Web-search. The standard depth-first algorithm has some insufficient that include dead circulation and low recall-precision. It provides a developed depth-first algorithm to improve the recall-precision and accuracy of search, and use it to search in small and medium-sized websites.
