For more info , see [[Filter]]. To test the filters , make sure you have the Filter sidebar visible (you can select this in the View menu ), and select the custom filter you made, before clicking on Find.
Example: People with surname Doe and who lived in Illinois State:
===Hier wordt de logica verklaart....===
If that filter excists, the logic would be: # make place filter1: state = Illinious# make event filter1 which is an or combination of three other event filters: (type= residence or type = death) and ( events matching place filter1)# make person filters: persons satisfying event filter1.
The extra filter is not that hard, the code is present in trunk (gramps 3. 0) to easily add that
