Subject: Help. Choosing shard keys

Hi to all,

I hope that from the group could help me to choose my shard keys. I
have two models that i want to shard.

The first model is a word list and it only have two fields into the
model: Language as char field and word as chard field also. I think
the best solution is to choose the field word for sharding here.

The second modelo is a book list and this have the following fields:

id, created_at, title, publisher, publishdate, source. Here I have
many doubts with the best choice.

I hope that you could help me because as the documentation said "It is
important to choose the right shard key for a collection. If the
collection is gigantic it is difficult to change the key later"
