The General tab allows you to set a Keyword Type as a required keyword. To make a keyword required, select Required keyword. You can select either Warn and continue or Warn and cancel from the Warning Level drop-down list to determine if you want users to be able to continue a query that does not specify a value for a required keyword. You can also click View Window Info Tree to access the Info Tree dialog box. This dialog box can be used to identify fields to map to Keyword Types.
