--- Comment #9 from Nick Clemens <nick at bywatersolutions.com> ---
I think you are correct, ES will default to *.*, however, I think having an
'_all_fields' and searching that directly gives us a little more flexibility.

Currently fields like 'nonpublicnote' are indexed and searchable, even if
hidden from the opac. Using the all field would allow us to keep those fields
in the full record stored in ES and search them from the staff side while
removing them from the opac side

I believe for boosting we could stil search:
"fields" : ["_all_fields", "title.*^5"],

Thoughts David?
