The Minus Operator
Click here to view the support page
For example, you want to find all information on a certain topic except for the information that has been developed in a certain project. Use the Minus operator to exclude certain terms from your search, e.g. like this:
Cost reinforced concrete 2020 -projectname_1
offer 100 licences -customer name -person
It is important that the term to be excluded is placed directly (without spaces) after the minus. If there are several comments to be excluded, the minus operator must be used several times (see 2nd example).
In addition, the minus operator cannot be used alone.
