Search engines are tools on the Internet to help you locate information about a specific topic. When a request is made, a metacrawler sends your queries to several databases. Most search engines are directory based or content based. Directory based search engines organize Internet resources into categories based on key words in the title or description of the page. Content based search engines locate Internet resources by examining the contents of each page and organizing the words it finds on an index page.
Search engines update their information on varying schedules.
Therefore, it is important to submit a search to several search engines to achieve the best results. Use quotes for phrases 3. Use the title word 5. Each search engine has its own unique strategies for conducting an advanced search. Refer to the User's Guide for Conducting an Advanced Search on the Internet and practice using the different search engines by completing the activities.
