first of all thanks for these notes; there are very helpful.

Regarding the "one to N relations" example, I suggest making a minor update or adding some description of possible side effects.

In the example provided, where artist is "embedded" in the albums ids, between ":" separators, I'd suggest using this:

{
  "include_docs": true,
  "startkey": "artist:tom-waits:",
  "endkey": "artist:tom-waits:\ufff0"
}

instead of this (note there is no ":" after the value on startkey)

{
  "include_docs": true,
  "startkey": "artist:tom-waits",
  "endkey": "artist:tom-waits:\ufff0"
}

The current example would return albums for any artist whose name includes tom-waits; e.g. tom-waitson which is probably not what's intended.
It may not be an extremely common scenario but since the artist is already put between ":" separators in the albums' ids, it may be a good idea to restrict startkey by that separator as well?

Regarding the "one to N relations" example, I suggest making a minor update or adding some description of possible side effects. In the example provided, where `artist` is "embedded" in the `albums` ids, between ":" separators, I'd suggest using this: ```json { "include_docs": true, "startkey": "artist:tom-waits:", "endkey": "artist:tom-waits:\ufff0" } ``` instead of this (note there is no ":" after the value on `startkey`) ```json { "include_docs": true, "startkey": "artist:tom-waits", "endkey": "artist:tom-waits:\ufff0" } ``` The current example would return albums for any artist whose name includes `tom-waits`; e.g. `tom-waitson` which is probably not what's intended.
