A query diagram is a project-based diagram whose entities can be searched for through the kin type strings. Like with the standard diagram, here as well you can create a project before creating the actual diagram (see paragraph Section 2.1 ).
To create a query diagram:
File menu > New Diagram of Type > Query Diagram; a new page of the application will open, with some panels: Diagram Tree, Project Tree (on the left), Kin Type Strings (on top).
This type of diagram allows you to search for entities within the entire KinOath Kinship Archiver database.
You can make your query in two ways:
you can use the kin type definitions seen above with the freeform diagram, together with labels (names, dates, etc.). See the example below:
The entities you have searched for are now listed in the Diagram Tree tab.
you can make your query even more detailed:
Panels menu > check the item Search Entities > the tab will appear next to Diagram Tree and Project Tree tabs.
Enter the name of the entity you want to find into the white string > press Enter or click on Search > all the entities somehow related to your query will be there listed.
Take the specific entity you are looking for and drag it to the Kin Type Strings panel, preceded by 'E' or 'x', which stand for 'undefined ego'. This will appear on the main panel. Add other kin strings if you want to modify your query.
To save the diagram: see Section 2.1, point 6.

Note The application contains a couple of sample query diagrams, named Query Diagram Syntax and Haemophilia in European Royalty, reachable via File menu > Open Sample Diagram.
