Chapter 5. Creating Data Reports > Extending a Found Set

Extending a Found Set

Once you have a found set, you might want to further refine it by finding records within the set or adding more records to the ones already found. In versions of FileMaker prior to version 6, you would use the Modify Last Find command, which would re-create the previous find criteria and allow you to modify them. That works just fine if your criteria are simple, but can create some serious issues if they are complex. For example, imagine that you created a found set of customers in the six New England states with billings over $500 per year. Now you want to find out how many in this set spent more than $1,000. A simple task, but tedious. You'd have to select Modify Last Find and change the sales amount for all six requests to $1,000. But in FileMaker 7, you have the ability to find records within the previous find (Constrain Found Set) or in addition to it (Extend Found Set) when you use the Modify Last Find command.
