Depending on what your goals/expectations are, it could also be worth noting the `expand.q` and `expand.fq` params, which are applied when fetching "expanded docs" (intersecting with the union of `expand.field` result values). In cases where you want to "pivot" to an unrestricted set of related clustered results, it may be helpful to specify `expand.q=*:*`, or something similar.

Is there some issue with the 'expand' feature?
