Applies the next by* method to the previous by* method, so
that a call
hasNext,
next, or
results sees only the intersection of the two
calls.
For example,
service.onlyType(Image.class);
service.byFullText("foo");
service.intersection();
service.byAnnotatedWith(TagAnnotation.class);
will return only the Images with TagAnnotations.
Calling this method overrides a previous setting of
or or not. If there is no active queries
(i.e. activeQueries > 0), then an
ApiUsageException will be thrown.
