Pg Full Text search in the ORM

[Stats Student]

Hi, does anyone know how to translate the following query to the ORM?

select * from company where to_tsvector(name) @@ to_tsquery('gold:*')

So far I have the following, but cannot seem to integrate the [:*] piece.

Company.objects.annotate(search = SearchVector('name')).filter(search = SearchQuery('gold'))

TIA
