I'm a newbie in elasticsearch, so my question is:
There are 3 sections in bool filter:
must All of these clauses must match. The equivalent of AND. must_not All of these clauses must not match. The equivalent of NOT. should At least one of these clauses must match. The equivalent of OR.
How do I perform a "should_not" query?
Thanks in advance 🙂

In order to get something like "should_not" please try the following query:
In this case the clause "must" is required to retrieve the all results (the result with the city "XYZ" too) but with decreased score for this specific one.
