| Abstract: | Web Search Engine is an fast and primary tool for locating special information among huge amount of information resources on Internet. The status and development of the Web search engine are discussed in this paper, through the case of development of full text retrieval system for ChIN (Chemical Information Network) Web pages. The full text retrieval software Isearch is employed in the full text retrieval system for ChIN, based on the analysis of the search mechanics and the comparison of some search engine softwares. A case study of development of the full text retrieval system for ChIN is given in this paper. |
