From the docs:
> 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 exact by setting
search_fields to ['first_name__exact']
However, when I do this for any DecimalField, and enter any non-parsable
(as a Decimal) value in the search box, I get the following:
{{{
