Abstract: In this paper we propose a method to get the exact output for the query what a user enters, Since the search process becomes in-effective nowadays. To overcome this problem we can subdivide inferring process into different steps. When the query is submitted to the search engine, the query is forwarded to analyse. Analysing process is based on number of search results for that particular query and click through log is obtained. A framework is discovered from user click through log to cluster feedback session. From feedback session pseudo documents are generated to cluster search goals. Then CAP is formulated to evaluate the performance of inferring user search goal.

Keywords: Click-through Log, Feedback session, Pseudo Document, Calculate Average Precision.
