PAF allows you to search on various criteria. For example, to search for all records that contain a perticular word or phrase in the Notes, you can use: Search > Advanced Focus Filter > Define > Notes (click on ">" to move it to the right-hand column) > Contains (whatever word or phrase) > OK > OK.
In the same way you can search on names and places or combinations of them.
If you put a checkmark by "Show results only", it will hide names that have not been selected (until you remove the checkmark). This makes it easy to find the record you are looking for.
