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 `Lexeme`s together either ANDing, ORing instead of just
letting the user specify the query as a postgres string
(https://www.postgresql.org/docs/9.6/static/datatype-textsearch.html
#DATATYPE-TSQUERY)
{{{
Dog.objects.annotate(search=SearchVector('name')).filter(search=RawSearchQuery(Lexeme('opt',
prefix=True) + Lexeme('blah', invert=True))
}}}
