How to do a case-sensitive search in Preview application? Is it possible to perform a case-sensitive search in Preview?

For example, I'd like to find all occurrences of the text 


  LAST


but not 


  last 


or 


  Last


I tried enclosing term in double quotes to no effect: 


  "LAST"
In preview there is no option for case sensitive search , but you can use the mac third party apps from ADOBE where you can get more search options like case sensitive,stemming ..etc More reference use this
