I have a MultiSearch query over multiple types with multiple fields per type. I see that I can add a .SuggestPhrase() to an individual SearchDescriptor on an individual field, but not to an entire search query. How can I apply a Phrase suggestion to a multisearch query? Ideally it would be applied to all fields that are being searched on.
My use case is this: A user performs a MultiSearch query. They didn't find what they wanted. At this point I'd like to suggest a different query that might be what they're looking for. This would be similar to Google's "Did you mean..." recommendation.
