**Expressing a search domain (args)**
|
||
|
||
Each tuple in the search domain needs to have 3 elements, in the form: **('field_name', 'operator', value)**, where:
|
||
|
||
* **field_name** must be a valid name of field of the object model, possibly following many-to-one relationships using dot-notation, e.g 'street' or 'partner_id.country' are valid values.
|
||
* **operator** must be a string with a valid comparison operator from this list: ``=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right``
|
||
The semantics of most of these operators are obvious.
|
||
The ``child_of`` operator will look for records who are children or grand-children of a given record,
|
||
according to the semantics of this model (i.e following the relationship field named by
|
||
``self._parent_name``, by default ``parent_id``.
|
||
* **value** must be a valid value to compare with the values of **field_name**, depending on its type.
|
||
|
||
Domain criteria can be combined using 3 logical operators than can be added between tuples: '**&**' (logical AND, default), '**|**' (logical OR), '**!**' (logical NOT).
|
||
These are **prefix** operators and the arity of the '**&**' and '**|**' operator is 2, while the arity of the '**!**' is just 1.
|
||
Be very careful about this when you combine them the first time.
|
||
|
||
Here is an example of searching for Partners named *ABC* from Belgium and Germany whose language is not english ::
|
||
|
||
[('name','=','ABC'),'!',('language.code','=','en_US'),'|',('country_id.code','=','be'),('country_id.code','=','de'))
|
||
|
||
The '&' is omitted as it is the default, and of course we could have used '!=' for the language, but what this domain really represents is::
|
||
|
||
(name is 'ABC' AND (language is NOT english) AND (country is Belgium OR Germany))
