Hi,
I can understand that you need additional + before the search-words to get a "real"
AND, but what confuses me is that
10060 && 10040
(which should be the same as AND) does a real boolean AND like
+10060 AND +10040
In the query syntax docu, you read "The symbol && can be used in place of the word
AND.". But it is totally different. How do I explain that to my users?

Hi,
To achieve what you want, you need to use the required operand (+)
