Go to Find, type Smith in name, New Record/Request, type Parker in name, perform find
This will find both Smith and Parker
Thank you I didn't realise you could do this. Problem sovled straight away. I now have a 5 step process of adding requests but I am having trouble putting this into a single script. I have tried using the Extend Found Set function but this doesn't allow me to specify multiple searches in the same field. If i use the Extend Found Set function again after that it seems to reset the Find and not work. Any ideas?
Enter Find mode
Set field // enter your first set of criteria
Set Field // enter your second set
Set Field // enter your third
//...and so on to get 5 requests
Set Error Capture [on]
Perform Find 
This is the scripted version of what David described in his post.
