At present, the search engine is an important component of the Internet; it is also a hot research topic in the intelligence information processing field. The study of the fast search engine's essential algorithm and the realization mechanism has certain academic significance and practical application value. The indexer's construction of complete Chinese website retrieval involves the selection of index's data structure. Inverted file is the commonly used data structure of large-scale Chinese web site retrieval. The research's hot spots are How to generate the inverted file, and how retrieve quickly in the inverted.This article first expatiated the search engine's organizational structure, the principle and the realization mechanism, from the construction homepage database, the dictionary database, to the participle algorithm, the establishment characteristic database, the index database, as well as the establishment based on the mechanism of the fast index, inspected the essential construction of data and the fast algorithm, and tested the system's performance through certain homepage database, and got a satisfactory result. Finally, introduced the characteristic of the mobile search, the pivotal technology of the mobile search and the relationship between the mobile search and 3G, designed a mobile search model which could be applied to 3G network based on inverted keyword file in addition. The model adopts retrieval method based on inverted keywords file, meanwhile, takes into account the characteristics of the Mobile terminal screen's small size, and then cuts up the searched-webpage, extracts the topic region which is most relevant to query requests to the users, so that the mobile users could conveniently get the accurate Web information.The key point of the paper is the produce of the structural dictionary which convenient for binary search, improved the cut word algorithm greatly based on the dictionary, and constructed the relationship among the dictionary, the index and the inverted list, designed a mobile search model which based on inverted file.
