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:
{{{#!python
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!
