چکیده مقاله:
Information retrieval can be achieved through computerized processes bygenerating a list of relevant responses to a query. The document processor,matching function and query analyzer are the main components of an informationretrieval system. Document retrieval system is fundamentally based on: Boolean,vector-space, probabilistic, and language models. In this paper, a new methodologyfor matching function of Boolean retrieval systems is proposed and tried to extendpostings list data structures and increase the efficiency of using postings lists andskips. The final effect of these considerations is in decreasing the search time.
