Parses the one legacy lookup spelling this port still carries.

Python accepts a whole family of <c>field__operator</c> lookups. Only
<c>name__contains</c> survives here, as a migration aid for callers porting
keyword-argument filters. New code writes an expression and lets translation
build the document.

This deliberately diverges from Python: there, an unrecognised
operator falls back silently to an exact match. Answering a
different question than the one asked is the failure this port
refuses.
