1779 **Expressing a search domain (args)**
1781 Each tuple in the search domain needs to have 3 elements, in the form: **('field_name', 'operator', value)**, where:
1783 * **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.
1784 * **operator** must be a string with a valid comparison operator from this list: ``=, !=, >, >=, <, <=, like, ilike, in, not in, child_of, parent_left, parent_right``
1785 The semantics of most of these operators are obvious.
1786 The ``child_of`` operator will look for records who are children or grand-children of a given record,
1787 according to the semantics of this model (i.e following the relationship field named by
1788 ``self._parent_name``, by default ``parent_id``.
1789 * **value** must be a valid value to compare with the values of **field_name**, depending on its type.
1791 Domain criteria can be combined using 3 logical operators than can be added between tuples: '**&**' (logical AND, default), '**|**' (logical OR), '**!**' (logical NOT).
1792 These are **prefix** operators and the arity of the '**&**' and '**|**' operator is 2, while the arity of the '**!**' is just 1.
1793 Be very careful about this when you combine them the first time.

1799 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::
