Documentation configuring multisearch

[rubenvoss]

When I used the following standard options for configuring the multisearch:
PgSearch.multisearch_options = { using: [:tsearch, :trigram], ignoring: :accents }
I got this error: (Object doesn't support #inspect)
and I had to drop, create, seed db in rails.

These are the options that worked for me, after dropping my db 5 times:
PgSearch.multisearch_options = { using: { tsearch: { prefix: true } } }

I suggest changing the readme to this
thanks 😁
