A logical OR. 

**Example**

The following expression returns true if `A` matches `B` or `A` matches `C`:

`where "A" matches "B" || where "A" matches "C"`

In Cloud SIEM, both sides of the `||` must be boolean. Other values such as string are not supported when using a logical OR operator.

### !

The exclamation point (!) function is equivalent to a logical NOT operator.
