\class QLandmarkUnionFilter
\brief The QLandmarkUnionFilter class provides a filter which unions the results
of its constituent filters.
\inmodule QtLocation
\ingroup landmarks-filter
\since 1.1
Conceptually it performs an OR operation and may thus be used
to select landmarks which match any one of it's constituent filters.
Whether a union filter can be comprised of
compound filters (i.e. union or intersection filters) is backend specific.
Even if this is supported the performance of such a filter is likely to be poor.
