>Yeah, I wanted to mean a tag with more than one field. Something indexed on customer+products+date .

Well thats OK. You just define your tag based on a concatenated column expression, define a meaningfull name in the cmLookupManager.GenTagList method and presto, the multi tag expression is in your list of available lookups that the user can select from the find dialog.

>OK. You wouldn't use the find toolbar button, then. You would call this from somewhere else ?

Well, you could subclass the form's find method so that you call you own custom find dialog where the find criteria is like this or, just create a specialised find method on the form or in the CDE and have a command button on the form that executes your specialised find method when you click it. So, you can have your subclassed list, standard tag based find dialog and specialised find lookups all on the same form. They are not mutually exclusive or anything like that.
