Using AND, OR, and NOT
If you want to refine your search a little, you can use special search operators in your search criteria to get more specific.
  • AND searches for documents that have both words in it.
  • OR searches for documents that have either word in it.
  • NOT eliminates documents where the word is found.

Using Parentheses and Quote Marks
Use parentheses or quote marks to specify the order of evaluation to the search engine.

  • Parentheses determine how ANDs and ORs are treated. Words within parentheses are considered as a unit, and are considered first.
  • Quotation Marks are searched for literally. This is useful when you want to search for the actual words "and" or "or".

Using Wildcards
Wildcards are used to perform searches based on incomplete words or phrases.

  • * - the "*" character represents any number of characters. For example, searching on Law* would return Law, Lawyer, Lawson, etc.
  • ? - the "?" character represents any single character. A search for ?ar?et would find both carpet and target, but not Learjet.

Case-Sensitivity
By default, all searches are not case-sensitive, unless the search criteria is entered as mixed-case.
