the quick brown fox jumped over the sleeping dogI was just doing that
to troubleshoot/discover. I knew that you couldn't copy-to-copy but,
apparently, needed to be reminded.
My end goal (which I don't think I can achieve?) was to get my
everything field to contain something like:
everything: [ 'the quick brown fox jumped over the sleeping dog',
'quick brown fox jump over sleep dog']
So that a single/simple query would match that doc for q=dog or q=jump
or q=sleeping and would score extra high for "the dog jump", but I
guess I will need to change the query logic to search on both fields.
