The framework I use sends parameters to a standard lookup form, with an (initially empty) grid. Incremental search is supported.

More than one field (or expression) names are sent as a single parameter, separated with ";". Descriptions are sent in a separate parameter. The standard form has, among other things, a button to invoke the associated form (e.g., if the user looks up a client, and the client doesn't exist yet, the user can immediately create a new client, in the client form).

All this is quite ambitious (which is why you should consider buying a framework), but I hope I have given you some ideas.
