Syntax of domains - operators

Question

I want to know how to do difficult domains with operators, because if I have something easy as:

(A & B) --> ['&', ('id', 'in', active_ids), ('partner_id', 'in', partner)]  I know to do it
But if I have
(A & B) | C  or
( (A & B) | C) |  (D & E)  I don't know how to do it, because I don't know where I have to put the operators

Hello Celia,
Odoo use polish notation to manage all filters and its operator between two filters. For that you need to have a look inside polish notation if you dont know anything about it. http://en.wikipedia.org/wiki/Polish_notation [1]
From your question : ( (A & B) | C ) | (D & E) will be formed as like below to manage domain inside Odoo.

1) [ '|', '&', '|', '&', (A), (B), (C), (D), (E) ]
2) [ '|', '|', '&', (A), (B), (C), '&', (D), (E)  ]
3) [ '|' , '&' , (D) , (E) , '|' , '&' , (A) , (B)

I guess the #1 results in:
(((A & B) | C) & D) | E
doesn't it?
