This isn't in the hashed index section which means it's probably a bit out of place, and also I thought re: our conversation yesterday, you couldn't use "hashed" index on multi-key fields.

You cannot create a hashed index on an array.
You can create a hashed index on apparently any other BSON type (so a: {b: {c: {d: 1, e: 2}}} is a valid document for a hashed index.

So "for fields that hold arrays" (which would be a multi-key index) is misleading or confusing?

Removed references to arrays, which I thought I'd done already.

I think there a few things in this list that should still be changed. (It's ok to --amend commits in pull request, but then you have to push -f..) |
