Searching
  • Use search engines to find webpages

  • Search engines have programs that search the web for pages and data.
  • Not all data is webpages

Searching
  • Type some keywords into the space given.
  • The search engine will look for pages with those keywords
  • Some require AND’s between words, some don’t (like google).
  • The results will be displayed.
displaying search results
Displaying Search Results
  • Generally the results appear as a list of links.
  • There may be several pages of results.
  • There may be short excerpts from the document.
  • There may be a cache.
  • There may be options to download.
  • There may be other links or suggestions on the page.
subject indexes
Subject Indexes
  • Example: Yahoo
  • Hierarchical menus that let you find the subject you want.
  • Eg, Tennis elbow :
    • Health ->Diseases ->Sports ->Tennis Elbow
  • Search by idea rather than by exact phrases.
meta searches
Meta searches
  • Metacrawler searches other search engines for your query
  • It waits a few seconds, then displays the top results from each
  • Can be useful since different search engines use different methods for finding and categorizing pages.
