Searching on multiple phrases with or using searchkick

Question

I have the following phrases for example:

phrases = ['foo bar', 'baz qux'] Using rails searchkick, how can I get matches that have any of those phrases in any of the fields?

I have tried this

Model.search('foo bar baz qux', operator: 'or') and this Model.search(['foo bar', 'baz qux'], operator: 'or')

and this returned matches of any word, not the phrases.
