Two separate expressions can be combined with AND in one field
While quick search supports the use of AND, you do not need to include "AND" between criteria items, because a blank space will always be interpreted as an AND operand.
Two separate expressions can be combined with OR in one field
Can be used with all criteria; NOT *pump, NOT NULL, <> A?
The search option "Document and Folder Properties" does not search for Environment Attributes.
You cannot modify the three default options.
So if you want to search Environment Attributes, but NOT a full text search, you have to add a new search setting by yourselves.
I have one created to search for: "Document and Folder Properties" + Environment Attributes
