Filter Search Specification Syntax in Backus-Naur Format

Users can perform filter searching through the user interface controls (exposed through a special filter applet), or specified in the filter search Specification property of the Search Definition category. The syntax is slightly different when done through the user interface, but in all cases the syntax is simple BNF (Backus-Naur Format).

Examples

• : condition
• : expression

NOTE:  Searches on filter fields from the UI do not support the logical operators AND or OR.
