Your error message says that the current app engine API doesn't
support 'OR', and
the docs state:
'An entity must match all filters to be a result. In the JDOQL
string syntax, multiple filters are specified separated by && (logical
"and"). Other logical combinations of filters (logical "or", "not")
are not supported.'
So it looks like you'll have to assert your conditions on the fetched
result set.
If the returned results are too many in number, you can use the query
operation setRange
to reduce the number returned...
