Improve the performance of your duplicate case search and limit the number of potential
    duplicates by defining basic conditions for potential duplicate cases.
    
      Add a Search duplicate cases shape to the life cycle of your case type. For more
        information, see Finding duplicate cases.
     
    - 
        In the navigation panel of Dev Studio, click Case types, and then click the
          case type that you want to open.
      
- 
        On the Workflow tab, click Life
          cycle.
      
- 
        Click the Search duplicate cases step for which you want to
          define basic conditions.
      
- 
        In the step property panel, click + Add basic condition.
      
- 
        In the Potential duplicate, Comparator,
          and Current case fields, enter property names and values that you
          want to use in a comparison against existing cases, to determine duplicates.
        For example, to compare your case with all cases that contain the same email
          address, complete the following actions: 
            - In the Potential duplicate list, click
                Email.
- In the Comparator list, click is
              same.
 
- Optional: 
        To add more basic conditions, perform the following actions:
        
          - 
            Click +.
          
- 
            In the Potential duplicate,
                Comparator, and Current case fields,
              enter property names or values that later determine duplicates based on a comparison
              against existing cases.
          
- Optional: 
            To mark the case as a potential duplicate only when it meets all basic conditions,
              in the field below When, select
              and.
          
- Optional: 
            To mark the case as a potential duplicate when it meets at least one basic
              condition, in the field below When, select
                or.
          
 
- 
        Click OK.
      
- 
        Click Save.
      
The system evaluates the basic conditions first to limit the
      list of potential duplicates. The case must meet the basic conditions for the system to
      consider weighted conditions. For more information, see Defining a threshold with weighted conditions for a case type.At run time, users can
        decide whether to close a case as a duplicate or ignore the potential duplicate and
        continue. A dialog box provides the reason for marking the case as a potential duplicate,
        which helps users make an informed decision.
