A couple of points (using 3.6.1 in production, and an experimental 3.8.??? 
in my sand box) and after cataloguing your Richard Louv title, and using 
both staff and OPAC:

Searching for "nature defecit" *with* the double quotes fails -- this I 
expect, as the quotes eliminate fuzziness.

Searching for nature defecit (no quotes) works perfectly.

Searching for "nature-deficit" (with quotes) fails; I am only 
semi-surprised as the logic of the - (minus sign) is to search for the 
phrase without the term after the minus.  However +nature -deficit also 
finds that title alone and in my opinion should not (but my opinion is not 
definitive.)

I also tested with a phrase a little more common to our catalogue:  British 
Navy

British Navy ==> 1636 results

"British Navy" ==> no results (this I must look into, I am very surprised 
as it actually exists in the catalogue written with the quote marks on 
several occasions.)

Britsh Navy and British Nevy both ==> 1634 results (have not yet found 
which two (if the same two?) are missing.

But ... Britsh Nevy (double typo) finds 1637 ... weird.
