    Information Retrieval Techniques used by the Midnapore College (Autonomous) Library Users: A Study
    (INFLIBNET Centre, 2014-09-25) Dutta, Avijit; Das, Subarna Kumar
    This paper aims to present the results of a survey conducted to determine the information retrieval techniques used by the teachers and students of Midnapore College library. The paper examines the result from a questionnaire-based survey conducted at the library. 100 samples of the questionnaire were distributed randomly between the staff and students of the college out of which 93 completed and received for analysis. The study reveals that a significant number of users search information regarding the library material through OPAC despite encountering problems. Lack of basic skills among users was found to be the major reason for not utilizing full features of OPAC, improper query formulation and non use of search operators while surf the web. It is suggested that library should organize quality instruction programmes to improve knowledge and skills of the users.

    Role of Meta Search Engines in Web- based Information System: Fundamentals and Challenges
    (INFLIBNET Center, 2006-11-09) Das, Subarna Kumar
    Meta search engines are powerful tools that search multiple search engines simultaneously. Unlike crawler-based search engines such as Google, AllTheWeb, AltaVista and others, meta search engines generally do not build and maintain their own web indexes. Instead, they use the indexes built by others, aggregating and often postprocessing results in unique ways. Meta search engines accept your query, and send it out to multiple search engines in parallel. They are often quite fast, using private “backdoor” servers made available by the search engines they query. They get this privileged status thanks to revenue sharing agreements. There are several advantages to using meta search engines, though they’re not always the most appropriate tool. The most obvious advantage is that you can get results from multiple search engines without having to visit each in turn. Apart from the time savings, there is some evidence that this gives your search a broader scope, since each individual search engine’s index differs from all others. Present paper attempts to highlights the role of meta search engine in web- based information retrieval
