The Perfion Query - Known Issues

Hierarchy-Notation combined with Feature Wildcards

When combining Hierarchy-notation with Feature Wildcards at the innermost level it does not work, i.e. for queries of the following type (where the Wildcard and Hierarchy-notation is applied right before the Property):

*{String='Motor Vehicles'
(102,104,200){String='Motor Vehicles'
Category.*{String='Motor Vehicles'
Category.(102,104,200){String='Motor Vehicles'

Since the use of Feature Wildcards is used to query across multiple features and hence can be expected to yield many results, combining this with the Hierarchy-notation would most likely yield very poor query performance, so this combination would not be recommended anyway.
