Comment (by charettes):

 We could be extra safe and always cast the expression to text in a
 `CAST(expression, output_field=models.TextField())` but I don't understand
 why you're using FTS here, using `LIKE` through the `__contains` lookup
 would be more appropriate IMHO. In the meant time you can take care of
 casting the expression yourself before annotating your queryset to work
 around your issue.
