Using Regex for specific filter: Exclude symbols
In this example we want to exclude everything that contains @ or /
To do this, we will use the following Regular Expression:
^((?![@/]).)*$
Breakdown of the Regex elements used
| ^ | Beginning of the string |
| () | Capturing Group |
| (?!) | Negative look ahead. This specifies a group that cannot match after the main expression.
(i.e. if it matches, then the result is discarded) |
| [] | Matches any character in the set |
| @/ | Character |
| . | Matches any character except line breaks |
| * | Match 0 or more of the preceding token |
| $ | End of the string |
Practical case
We can now use the expression explained above to single out group members.
The Filter By Regular Expression option will be used to exclude everything that contains @ (for emails) or / (for users).
Click on the filter icon  and select Filter By Regular Expression.
Having used the expression ^((?![@/]).)*$ to filter the column, all lines that contained the symbols @ or / have now been excluded.
