Search Strategies Basic

      This week was very interesting because we learnt, When should we use keywords, subject headings,phrases, single words? Selecting keyword is used when you're first starting to formulate your research question.

     Also we have learned examples of subject headings;
     a. Library Subject Headings;Used as the "official vocabulary"
     b.Science Subject Headings;Used to describe the content of documents in the Library at AIU
     c. Thesaurus of Psychological Index Terms;used by American Psychological Association indexers to describe the content of documents in the database.

   In addition to that we learnt Boolean Operators, its definition and how it works.
          examples are;
                               a. AND; is used in between words you limit the search.                                     b.OR;is used in between words it expands the search.
                               c. NOT; is used in between words and excludes a word       from search.
