Immediately after the find try interrogating SEARCH_COUNT
It can be useful to stop unnecessary processing if the search doesn't find anything
IF SEARCH_COUNT >0 THEN .......
and if you need to persist the number during the process , try stuffing into a non persisting Bo Attribute because the number will change the next time you do a find on another BO
So CREATE NPBO WITH NPBO.Attribute1 = SEARCH_COUNT
