I've needed prefix matching in full text search. As in #27899, It would be nice to add a RawSearchQuery, but also to have it accept a Lexeme so your query might look something like

Dog.objects.annotate(search=SearchVector('name')).filter(search=RawSearchQuery(Lexeme('opt', prefix=True)))

and combine Lexemes together either ANDing, ORing instead of just letting the user specify the query as a postgres string (

Dog.objects.annotate(search=SearchVector('name')).filter(search=RawSearchQuery(Lexeme('opt', prefix=True) + Lexeme('blah', invert=True))
