  • What Is a Search?
    A search is the organized pursuit of information. Somewhere in a collection of documents, email messages, Web pages, and other sources, there is information that you want to find, but you have no idea where it is. The search engine gives you the means of finding that information.

    You conduct a search by issuing a query, which is simply a way of asking a question that will find the information you are looking for. Searching is often an iterative operating. You submit a query and if the results list does not contain the information you are looking for, you modify the query until you locate a page that contains the answer.

    Tools for Searching
    The search engine provides the following tools to help you find what you are looking for:
  • A search form to enter your query
  • Ways to broaden or narrow the extent of your search
  • A results list of pages that match your query

  • The search engine produces a ranked list where the documents at the top of the list are more likely to be relevant than the documents toward the bottom.

    The relevance of a document is based on how many of the search terms are present in the document, how frequently the search terms occur, and how close the search terms are to each other.
