Abstract


With the development driven by trends in the global tide of information , a text message is the most basic and most commonly used form of multi-information to increase indefinitely . Text information that they need to be able to find a lot of information , people will have to pay a lot of energy , research and development of an efficient unstructured text data , effective management and retrieval tool is imminent . Full text information retrieval based on text information to retrieve the object , depending on the data as a means of information retrieval . From analysis and study of the following sections : 1 , of the traditional full - text information retrieval method , inverted file , mixed indexing technology , introduced its principle and index file structure , and certainly its advantages , but at the same time also pointed out that its indexing speed and the fact that there are some gaps on the mass of information indexing need to create an index faster index file structure is necessary . 2 describes the basic flow of the index of full-text information retrieval system , and then designed the structure of the system index file and index principle , dynamic equilibrium tree indexing files and incremental index optimization consolidation strategy . 3, the design and development of full-text information retrieval system , designed a functional model of the system , and the system sub-module hierarchical development and design , the theory and practice of combining learning purposes .
