Subject Re: Use boolean operator "-", the result is incorrect
Date Wed, 08 Apr 2020 09:46:37 GMT
What is debugQuery telling you about:
- "rawquerystring"
- "querystring"
- "parsedquery"
- "parsedquery_toString"
- "QParser"

Also what is your default query operator, AND or OR?
This is what matters for your second example with  id:("1" "2")
It could be  id:("1" AND "2")  or  id:("1" OR "2") .

Regards
Bernd
