The search query can contain quoted phrases with spaces. For example, if a
user searches for ``"john winston"`` or ``'john winston'``, Django will do
the equivalent of this SQL ``WHERE`` clause:
.. code-block:: sql
WHERE (first_name ILIKE '%john winston%' OR last_name ILIKE '%john winston%')
If you don't want to use ``icontains`` as the lookup, you can use any
lookup by appending it the field. For example, you could use :lookup:`exact`
by setting ``search_fields`` to ``['first_name__exact']``.
Beware that because query terms are split and ANDed as described earlier,
searching with :lookup:`exact` only works with a single search word since
two or more words can't all be an exact match unless all words are the same.
Some (older) shortcuts for specifying a field lookup are also available.
You can prefix a field in ``search_fields`` with the following characters
and it's equivalent to adding ``__<lookup>`` to the field:
