Attributes: model (Model): The Django Model that this lookup channel will search for. plugin_options (dict): Options passed to jQuery UI plugin that are specific to this channel. min_length (int): Minimum number of characters user types before a search is initiated. This is passed to the jQuery plugin_options. It is used in jQuery's UI when filtering results from its own cache. It is also used in the django view to prevent expensive database queries. Large datasets can choke if they search too often with small queries. Better to demand at least 2 or 3 characters. NécCs&d|j|i}|jjjf|Žj|jƒS)aç Return a QuerySet searching for the query string `q`. Note that you may return any iterable so you can return a list or even use yield and turn this method into a generator. Args: q (str, unicode): The query string to search for. request (Request): This can be used to customize the search by User or to use additional GET variables.

Note that the order of the ids supplied for ManyToMany fields is dependent on how the objects manager fetches it. ie. what is returned by `YourModel.{fieldname}_set.all()` In most situations (especially postgres) this order is indeterminate -- not the order that you originally added them in the interface. See :doc:`/Ordered-ManyToMany` for a solution to this.
