Introduction: One of the ways to retrieve the expert information from internet is using search tools. This research was aimed to measure the relevance of documents retrieved from search and meta-search engines in the field of pharmacology. Findings help web users, especially pharmaceutics researches and specialists, to know the search tools cover more pharmaceutics information and use them to access the required information. Methods: In this descriptive research, 6 major search and 6 major meta-search engines, introduced by the website of www.searchenginewatch.com as well-used internet search tools, were chosen. Pharmaceutics keywords were chosen from medical subject Headings (Mesh) and then selected terms of pharmacology were searched in each of search engines. The first 10 results of search engines were selected for evaluation of recall and precision. Data were analyzed with Excel. Results: Yahoo retrieved the most pharmaceutics documents and scored the highest rank (34%). Aol had 62% precision and 21% recall and retrieved the most relevant pharmaceutics documents. Dogpile retrieved the most pharmaceutics documents and scored the highest rank (22%), followed by Metacrawler (21%) and Info (19%). Excite had 62% precision and 22% recall and retrieved the most relevant pharmaceutics documents. Conclusion: Search and meta-search engines are suitable tools for amateur or professional users and they have suitable search capabilities and facilities. Although using search engines in retrieving relevant documents is useful, but it is suggested that users follow the search in several search engines to access the relevant documents among the vastly available sources on web. Keywords: Medical Information Storage and Retrieval; Pharmacology; Internet.

Abstract Access to information is a fundamental element in research and production of science process, as well as one of the metrics of development. So, the awareness and use of communicational and informational networks, as well as their related technologies could be really necessary. In this connection, internet, web and related techniques, such as RSS (Really Simple Syndication, Rich Site Summary, or RDF Site Summary) is one of these technologies which appeared on many websites, weblogs and databases, in recent years and became the most expanded and suitable tool for making awareness. Obviously, this technology allows the librarians and information scientists to find access to the existential information on websites, weblogs and databases, in order to improve their commercial, economical, educational, research, social and cultural relations. More over, using this technology can make users to access to their information by themselves, and to fulfill their informational needs. This technology through its own language programming can show the latest information and become up to date by adding new information. RSS is a simple and quick method for current awareness, new book list, reference services, education and communication with users, which should not be ignored by librarian in libraries and information centers.Therefore, we tried first to give a definition of RSS feed as well as to present its advantages for application; then we try divide RSS readers into two main groups; web based and special software based, with some examples of each group. At the end, we suggest that for better understanding and also for providing appropriate and suitable information services for users, this technique (RSS Feed) and its facilities should not be ignored by librarians in the libraries and information centers.
