Search engine technology plays an important role in web information retrieval. However, with Internet information explosion, traditional searching techniques cannot provide satisfactory result due to problems such as huge number of result Web pages, unintuitive ranking etc. Therefore, the reorganization and post-processing of Web search results have been extensively studied to help user effectively obtain useful information. This paper has basically three parts. First part is the review study on how the keyword is expanded through truncation or wildcards (which is a little known feature but one of the most powerful one) by using various symbols like * or!. The primary goal in designing this is to restrict ourselves by just mentioning the keyword using the truncation or wildcard symbols rather than expanding the keyword into sentential form. Second part consists of the review on subdivision based on wildcards. It is based on the observation that documents are often found to contain terms with high information content which summarize their subject matter. The third part consists of a proposed algorithm based on the above two. The main goal of this paper is to develop a very efficient search technique by which the information retrieval will be very fast, reducing the amount ofextra labor needed on expanding the query. ©2009 IEEE.
