can you post example of what you are trying to find? there are different ways.
Do the first 'FIND' as normal from the keyboard and enter your first search value. Then instead of hitting 'return' to do the find under REQUESTS select 'ADD A NEW REQUEST' and enter the second value. Repeat adding requests for as many values you want to search for. Then hit 'return' or REQUESTS/ PERFORM FIND to complete find.
For example if you had a field "ANIMALS' and wanted to find all CATS and DOGS
Enter CATS in the ANIMALS field
REQUESTS/ADD A NEW REQUEST'
Enter DOGS in the ANIMALS field
REQUESTS/ PERFORM FIND to complete the find.
Carl is correct!
