Hi,
Can I use decimals smaller than 1 with the caret (^) notation on a multi\_match query?
Something like :
`"fields": ["title^3","text","extra_text^0.5"]`
Would this work as an "unbooster" for the field `extra_text`?
I can see that it does not raise an error but I wonder if it works as I expect.

That is correct.
