That looks like a correct syntax, but it's unlikely to use your index -
your index was created on to_tsvector('my_config', ...)

Try playing around with the example I gave, and try variations on it. Do
you understand why you have to supply a config when creating the
functional index? Do you understand the difference between
plainto_tsquery() and to_tsquery()?
