I have a Target per entity hierarchy with Book (B) being one of the subtypes.
It has two subtypes of its own - TextBook (TB) and EBook (EB).
I have a working dynamic query but I now want to filter for Books only - not TextBook nor EBook but of course GetEntityTypeFilter() returns a filter with all three values.
I understand the IS-A relation from an entity point of view (all 3 ARE Books) but is there better way I have missed rather than using a hard-coded value in a filter? ( ".Type == "B")
