VFP 6.0

I have a 'search' form with a listbox. First, the user picks something from a Combobox with a list of what to search on (via, Org, Name, Person ID, Auth Type), then the code visible the labels/texts accordingly. Once the text(s) are filled in and the 'Find' button is clicked, I want to list the search on the listbox. The trick is I need to do different things as well with different tables.

Lets say I want to do a search for Org $ 'Systems', I want to use the ORG table and list only two fields (org # and org name) with any wording included 'systems'.

Lets say I want to do a search for Name $ 'Smith', I want to use the PERSON table and list only one field (name) with any wording included 'smith'.

Etc...

Now, the next thing is how to correspond back to the correct table (index, recno(), ??) and then I do whatever coding thereafter.

The first thing that comes in my mind was to use SET FILTER TO but we know it's terrible slow. Anyone have ideas/suggestions to help me get started?
