Search engines

  • Limitations
    • A single search engine can only find a portion of the relevant web pages
    • Frequent changes in the web but the indexing process is slower
    • Rely on computer programs, yield irrelevant results due to language e.g. china

Search engines – how different?

  • Size – how much of the web is indexed
  • Scope – does it index in general or a specialized area
  • Formats – does it also index image, audio and video files
  • Currency – how often is it being updated
  • Ways of searching – can a complete sentence be entered in the search box
  • Results display – does it only display title
  • Results ranking – how does it rank search results
