One of information search based on text mining and EXTJS technology is provided, which uses the relative principles in the field of text mining and segmentation technology to preprocess and transform the information from internet. The problem of large data dimension caused by the redundancy characters extracted from the text is resolved and it improves the performance of the FE algorithm. Finally, the visual windows of results and easy operation web page interaction interface of management are showed and the burden of the CPU and memory of the server brought by the computing of the text mining is relieved by the new technology of EXTJS. The information decision system of the ceramic company testify that this method have the characters of Intelligent Behavior, precise result, beautiful and convenient interaction interface, easy operation and synchronization of running.
