Extending (broadening) a found set
Extending a found set lets you expand your search to include additional applicable records without starting over, if you’ve constrained a previous find request too much. To find records that match multiple criteria in the same or different fields (a logical OR search), perform a find, specify the next criteria, then choose Requests menu > Extend Found Set.
For example, after searching for customers in New York, you can broaden the search to also find customers in Hong Kong.
To extend or broaden a found set:
1.
Perform a find so that your database contains a found set.
See Making a find request.
2.
Switch back to Find mode and type the criteria to broaden the search.
3.
Choose Requests menu > Extend Found Set.
FileMaker displays the extended found set in Browse mode.
Example
To first search for customers in New York, and then broaden the search to also include customers in Hong Kong:
1.
Perform a find for New York in the City field.
2.
Go to Find mode and enter a second find request: type Hong Kong in the City field.
3.
Instead of clicking Find, choose Requests menu > Extend Found Set.
The found set would then consist of customers in both New York and Hong Kong.
