Query naming clash in 'One to N Relations'

[h4cc]

I implemented 1-n relations and got the following problem.
In the section https://github.com/eHealthAfrica/couchdb-best-practices#one-to-n-relations the example looks like this:

"_id": "artist:tom-waits:album:closing-time",

When using a query to fetch all artists, also the album relations will be fetched:

/_all_docs?startkey="artist:"&endkey="artist:\ufff"

In the section 'N to N Relations', the example does not have that problem because a own namespace friendship: has been used:

"_id": "friendship:person:avery-mcdonalid:with:person:troy-howell",

Would it be better to have a own namespace for the 'One to N Relations' too?

Any solution for this? or we need to change the structure of _id?

a colon ":" is \u003A,
in the querry switching \uffff for \u0034 would exclude some characters.
Can \uffff of \uff0 be used as separator tnsead of a colon?
so the _id would look like
"_id": "friendship\ufffperson\ufffavery-mcdonalid\ufffwith\ufffperson\uffftroy-howell"
