Description

My use case is that I'm trying to find phonetic patterns that rhyme using a database I built from the pronunciation dictionary CMUdict

For example:

Pronunciation.objects.extra(where=["code LIKE '%% - %%__1 - S T __0 D'"])

I want to be able to filter with % and _ wildcards in arbitrary amounts and places in the search string beyond just contains, startswith, and endswith, and the only way I could figure out how to do it is either to use a raw query or .extra - if .extra goes away I hope filter will support this behavior!
