It is difficult construct a query to identify pages within a hierarchy. For example, if I have the page [[CategoryX/CategoryY/Meeting]] and [[CategoryP/CategoryQ/Meeting]] I cannot identify the meeting pages via the following query:
{{query [[meeting]]}}
The only way to do this is
{{query “/Meeting”}}
i.e. a full text search. This works but is not superflexible, e.g. I can’t manage to combine it with “and”.
