The Documentation states that the various methods of the class openerp.osv.orm.BaseModel like browse, search, write, etc. can receive and return a single id/record.

Example: return value for browse method:

Return type: object or list of objects requested

Or select argument for browse method:

select -- id or list of ids.

Or return value for search method:

Returns: id or list of ids of records matching the criteria

I often have the feeling that this is not true and all methods allways expect and return lists.

Is my feeling wrong?

EDIT (in lack of comment functionality):

Thx, Mr. Reis. You are quite right! But is it also true for search?

EDIT:

Search always returns a list. The documentation is wrong. (Although the technical memento states it correctly).
