Meta-search engine a.Sends requests for information to several search engines simultaneously and compiles the results b.As the results are compiled, duplications are eliminated, thus yielding fewer results than a search engine B. Subject directories searchable databases that are developed andmaintained by human selection of sites to search broad subject categoriesand their descriptions1. Used in research and often linked to library systems2. Also referred to as research databases3. Mostly made up of thousands of specialized searchable databases, such as library catalogs and article databases4. Searches for non-HTML formats (PDF, Word, Excel, script-based, PowerPoint, etc.)5. Results in more reliable pages than search engines II. Internet Search Methods Four Categories A.

Internet Search Methods graphic organizerInternet SearchTools Individual search engine uses computer programs called spiders, crawlers, or robots to match key search words with the web pages that contain them. Returns a large amount of results, including duplicates Examples: Google.com the largest database of Web pages, Ask.com, Search.yahoo.comSearch Engines Meta-search engine sends requests for information to several search engines simultaneously and compiles the results As the results are compiled, duplications are eliminated, thus yielding fewer results than a search engine Examples: Google Custom Search Engine, www.excite.com, http://webcrawler.com Subject directories searchable databases that are developedand maintained by human selection of sites to search broadsubject categories and their descriptionsUsed in research and often linked to library systemsAlso referred to as research databasesMostly made up of thousands of specialized searchabledatabases, such as library catalogs and article databases Subject DirectoriesSearches for non-HTML formats (PDF, Word, Excel, script-based,PowerPoint, etc.)Results in more reliable pages than search enginesExamples: http://infomine.ucr.edu, directory.google.com,www.lii.org, www.about.com, EBSCOhost, libraryresearch.com,ERIC, CRIS, incywincy.com, completeplanet.com, Google scholar 5. Internet Search Methods graphic organizer INTERNET SEARCH TOOLS CONCEPT REVIEW1. List three types of Internet search tools. Search engines meta-search engines Subject directories 2. How does a meta-search engine like Google Custom Search Engine or Surfwax differ from an individual search engine like Google or Yahoo? Meta-search engines search multiple databases and compile the results. Meta-search engines return fewer, more concentrated results than individual searchengines. An individual search engine searches 1 database of information, whilea meta-search engine searches multiple databases simultaneously. 3. How are subject directories different from search engines? Subject directories require the user to locate directories and subdirectories andfind related web pages and documents based upon the categories selected. 4. Locate two subject directories on the web and list the URLs of your results. http://scholar.google.com/ http://infomine.ucr.edu/Answers will vary. 5. Why would you use a subject directory? Give two examples. A subject directory is used to search for documents in non-web format, such asPDF files, word documents, and photographs that have been scanned. It is usedto conduct research by government and academic institutions and industry. It isalso referred to as a searchable database. Possible student answers may include a student or a scientist conductingresearch for a project. Subject directory searches produce results such as research, white papers, andacademic information as opposed to individual and meta-search engines, whichproduce results such as web pages, businesses, and commercial sites. 6.
