The current large-scale centralized enterprise search engines face with a series of challenges. Such as the scale expansion, fast data update and user needs specialization and diversification. Thus, to establish an efficient, high-quality distributed search engine architecture in the area of oil-field and to realize data sharing based on ensuring does not destroy their existing enterprise search engine is becoming more and more important. In this paper, through analyzing the current situation of the search engines in oil-fields enterprise, and combining with meta-search engine technology, we proposed a reasonable solution about building distributed search engine architecture in the area of oil-field. To solve the existing problems of distributed search engine in application queries of the oil-field, this article mainly uses three technologies, such as interface specifications, query scheduling and ordering strategy.
