Had a question from Mark re a problem where the 'Search Clause Name' property on the Additional Field dialog is not appearing in the TRIM client.
I do not experience this behavior myself and I am not sure why it is happening. Best course of action is to either submit a formal support request or ask the question over at the support forum (http://community.hpe.com/t5/HPE-Records-Manager-and-HPE-TRIM/bd-p/itrc-1015#.Vqfh9yp97mE). If asking the question on the forum include a picture and what sort of user you are logged in on.
BTW, the support forum is much more suitable for questions given the ability to reply to comments.
