    The Advanced Query is now available in the Filter Assistant dialog box.
  2. Click Advanced Query .
    The Filter Expression Editor dialog box appears.

    This dialog box enables you to define a complex filter expression:

    • using the list of knowledge parameters initialized with keywords of the current chapter
    • combining AND/OR operators
    • using knowledge methods

    Depending on the selection of the knowledge parameters and its members from the Dictionary and Members of Parameters box respectively, all the members are listed in the Members of All box.

    You can use the Knowledge methods in the filter expression. For example, the following sample Knowledge methods Sup(x) where it means equal to x or equal to the value immediately superior to x and Inf(x) where it means equal to x or equal to the value immediately inferior to x are provided in PLMCatalogKwePackage.

    Note: You can implement your own Knowledge functions using Knowledge Advisor through CAA Knowledge language. These new functions can be added in PLMCatalogKwePackage. If the new functions are added in another package, to access these new functions in the Filter Expression Editor dialog box, it is necessary to load this package before opening the dialog box.

  3. Type the filter expression comprising the keyword, operator and value in the box.
