Lisa, The fields that represent values ($ fields) in the join criteria are the ones that need to be indexed, providing they qualify. You cannot really index a character field that is 255 characters in length or above.. Character fields that are indexed need to be of length 254 and below.
The idea is to design a good query around which you can build indexes that can be created if not already created.

If I use a qualification for the Join Criteria of ( 'Survey Number' = $Survey Number$) AND ( 'Network ID' = $Network ID$) AND ( 'TEIS Request ID' = $Request ID$), for optimal performance should each of these fields be indexed on each form? Or would it be OK for just one of these fields on each form?
