Example 1
                  
                
                  
               Result will be document that shows both
                activity 
                and university 
                the same document
                but if user put keyword as
                +activities university 
                note there is not "+" in front of 
                activitieswhich means 
                user pay attenttion to the word
                activities
                more than
                university it is found document  will have "activities" and the word "university" 
will or will not have in the document 
                  
                Example 2
                  
                
                  
                compare the number of found document in example 1 to example 2
               and the number of document in example 1 less than example 2
             because the example 2 search document that included the word  
                activities
                but not 
                university 
                
 
                  
                Example 3
                  
                
                  
                 the more users give conditions, the more users get specific result
                 
                      
                      
                      
			 
			Example 4
			 
			
			 means to find document that appear
            activities and
            university 
             but not  
            sport
                        
                      
                      
			 
			Example 5
			 
			
			 
			notice the different result from searching without 
            " "
			 
			Example 6
			 
			
                        
			 
			NoteØ : warning for using simple condition
			
           1. Simbol usage  ("+") or ("-") 
           Users need to add it in front of a keyword (without blank)
            for example
            +actvity -sport
             
			 
			2 .Use more than 1 word for keywords
             It make the result is more specific, meet all user' s requirements which 
means if user put more keywords, then user will get more specific result.
The order of adding symbol does not matter for the searching result. For 
example +actvity
            -university and
            -university 
            +actvity
            will get the same result
			 
			3 .Normally, Basic Search mention more than 1 keyword
           If user does not add the symbol ("+"/"-") and for example user put 
"activities university" means user asks for searching document
that included either or both 
            activities
            university 
            
            4 . If user cannot find document that have mentioned in the search box
                        
                          -  
			 
			 is might from many causes such as user use Basic Search with wrong 
conditions and user should try it again or user read user manual for the Basic Search again before the next try
             
-  
			 
			cannot found the specified document due to cannot found database
