I am a bit confused by the code below, are you really trying to model many
accounts in just  one document?

"account" is a document id,  indexes/indexing takes field names, not
document ids

the natural thing in u1db would be to have one db for accounts, and one
document per account, then index expression would just be:

expression: ["name <http://account.name>"]


another approach is to mix documents of different kinds in the same db, and
use a field "type": "account" etc to distinguish them, and put that in the
index as well
