We don't have test coverage for this at the moment. $text shouldn't be allowed against timeseries collections, we should investigate current behavior and see what happens if $text queries are issued against time-series collections.

It appears that geo won't be supported so we should write a few tests that ensure that $geoNear queries fail cleanly with an error message along the lines of,

"$geoNear, $near, and $nearSphere are not allowed against timeseries collections"
