By modeling for the fuzzy requirement information, the model for design retrieval is more adapt to the design reuse engineering fact.
并且通过对模糊需求信息的建模，使设计检索模型更适合于表达设计重用的工程实际。

A search engine of document information is improved and a heuristic search strategy with multithreading and distributing is implemented. It introduces fuzzyretrieval model on the object documents.
