How do I tell django to not escape % and _ in a query
headline__contains='%' would mean headline is anything, no?  In which case why include it in the query?
I want to be able to use wildcards in my django queries used for searching. However as the documentation says:

Entry.objects.filter(headline__contains='%')

Will result in SQL that looks something like this:

SELECT ... WHERE headline LIKE '%\%%';

How do I tell django to not escape % and _ in a query. Or is there another way to implement wildcard search in django (apart from writing the sql directly)?
