I think the way to go would be to OR connect single tags inside one
categorie and AND connect with other categories. Thus
'People > Mum'
'People > Dad'
'Event  > Christmas'
would yield the query:
SELECT Photos FROM Lib WHERE People='Mum' OR
                             People='Dad' AND
                             Event ='Christmas';

This is the way I would expect it. But for the future would be nice to
have some GUI to AND/OR/NOT connect the different tags. Probably
something with DnD of tags and AND/OR/NOT fields and maybe a natural
'Show all Photos from «Mum» and «Dad» at «Christmas»'
But this will get hard for custom tags ...
