Searching for information

• Size, complexity, and disorganization of the web makes search engine performance critical, and "search" one of the most popular links on most web sites.
• Scope of the search needs to be clear: whole site, section of the site.
• Organization, description, and redundancy of the search result links contributes to usability.
  ... Check fidelity.com for search results.
• Supporting information helps the visitor judge the relevance of the search results.
  ... Infoseek is a good example.
• Natural language search engines are getting attention but lack good usability.
  ... Try out AskJeeves.
