I deleted my collection and rebuilt it to check if there are any issues
with indexing. I didn't see any errors during indexing. My collection is
sharded and we use implicit routing...But after rebuilding my collection
also I am getting errors on group faceting. This is not happening all the
time but rather on small subset of data, which is fixed by reindexing.

Any suggestions on what else to check for??
