Search Strategies Basics and Boolean Search Basics

Search Strategies Basics
 
In this class Mr Azamuddin taught us about search capabilities and so on,, so we did some exercise on it and He showed us how to search information online effectively
so There are: brainstorming search terms, and Keywords in order to get information and find closely on internet
 
Examples of subject headings are:
       Library Subject Headings: Used as the "official vocabulary" of the Libraries catalog as well as many other library catalogs
       Science Subject Headings: Used to describe the content of documents in the Library at AIU as well as in catalogs other medical and health sciences libraries.
       Thesaurus of Psychological Index Terms: This controlled vocabulary is used by American Psychological Association indexers to describe the content of documents in the database.  These subject headings are sometimes called index terms or descriptors.  The library has copies of the printed volume and the thesaurus is also available online, searchable from within the database.
The following day , we were taught about one of well known search operator which is called BOOLEAN search operator
It is :
 
 
(named for George Boole, 1815-1864, a mathematician) - combining terms such as AND, OR, and NOT used in building a search statement or in putting several sets together.
 
Boolean operators are words that connect a search that may add or subtract a concept to your search. Boolean searching is the most common and basic search strategy.It allows you to expand (return more information or matches) a search by using OR or limit (return less information) a search by using the word AND. Most of the search engines on the World Wide Web allow you to use some form of boolean searching. The following list explains the basic boolean search strategies
 
Boolean Operator or Keywords


Boolean searching allows you to group words together in an electronic database or environment such as the World Wide Web to receive a number of different types of results. Depending how you group these word, you will receive different results.
