Indexing in search engines has been an active area of current researches. The main aim of search engines is to provide most relevant documents to the users in minimum possible time. So granting efficient and fast accesses to the index is a major issue for performances of Web Search Engines. Indexing is performed on the web pages after they have been gathered into a repository by the crawler. The existing architecture of search engine shows that the index is built on the basis of the terms of the document and consists of an array of the posting lists where each posting list is associated with a term and contains the term as well as the identifiers of the documents containing the term.
