You have the option of intelligently nesting your Find queries to perform a cascaded (multi-level) search of the trace results. Do this before starting the first Find by activating the option Search results in new window and leave the option for all other searches enabled. You then search successively for the various terms in the each of the recently opened windows, which further refines your hit list.
In order to generalize a query again, or to go back a step, simply close the most recent results window and return to the previous results window.
For more about the Find setup options, see the chapter Find.
