    • What is Google search?
      • Google Search is a full-text and most-used search engine which uses computerized spider/robot to index million of pages on the web.
      • The search results are generally presented in a list of results and the information may consist of web pages, images, videos and other types of files.
      11/11/11 Zanzibar University Library

      • www.altavista.com
      • www.alltheweb.com
      • www.ask.com

      • Analysis of your topic/question is crucial before entering into the search exercise.
      • The analysis of your topic/question should lead you to obtain subject headings and terms to be searched.
      11/11/11 Zanzibar University Library
    • Basic search…
      • In making the subject headings, terms and query try to think of:
      • Synonyms,
      • Variant spellings,
      • Plural and singular,
      • Broader and narrower,
      • Homonyms,
      • Acronyms.
      11/11/11 Zanzibar University Library
      • Search is always cAsE insensitive.
      • Search operators are case sensitive:
      • Generally, all the words you put in the query will be used.
      • Words that are commonly used, like 'the' 'a' ‘which’ ‘when’ 'for’ ‘of’and alike are usually ignored (these are called stop words).
      • A search engine is not a human, it is a program that matches the words you give to pages on the web .
      11/11/11 Zanzibar University Library
      • Describe what you need with as few terms as possible.
      • The broader the terms, the greater are the chances of getting both information relevant and irrelevant
      • Narrower terms usually give fewer result but most relevant
      11/11/11 Zanzibar University Library
      • Phrase search ("") By putting double quotes around a set of words, you are telling Google to consider the exact words in that exact order without any change.
      11/11/11 Zanzibar University Library
    • The * or wildcard operator
      • If you include * within a query, it tells Google to try to treat the star as a placeholder for any unknown term(s) and then find the best matches.
      • For example, the search [ Google * ] will give you results about many of Google's products
      11/11/11 Zanzibar University Library
    • ~ tilde operator
      • The tilde functions as a synonym search, returning not only the search term you specified, but also terms that Google “thinks” are synonymous with the term.
      • For example, the search [ Google trics~ ] will give you following results google trics, tips.. techniques..guide..
      11/11/11 Zanzibar University Library
      • Information searching in most database is based on the principle of Boolean logic (the logic of relationship among terms)
      • ( AND, OR, NOT)
      • Boolean operators improve search result by broadening, narrowing and excluding search results
      11/11/11 Zanzibar University Library
    • AND operator (+)
      • AND operator tends to narrow a search and make it focused. The more concepts combined in a search with AND logic, the fewer records will be retrieved.
      • Eg. search red AND picture cards
        • From this search you will find cards that contain both the given search terms.
      11/11/11 Zanzibar University Library
    • OR operator
      • OR operator broadens search result.
      • Eg. Search black OR picture cards
      • As a result you will get cards that contain one of the given search term or both
      11/11/11 Zanzibar University Library
    • NOT operator (-)
      • NOT operator exclude documents that contain the keywords a searcher would not like to appear in the documents.
      • Eg. Search black NOT picture cards
        • From this search you will exclude unwanted cards and find only not pictured black cards

      • Query modifiers are query words that have special meaning to Google. Typically these operators modify the search in some way, or even tell Google to do a totally different type of search.
