We're doing a review of several thousand alerts. About half of them have this syntax at the end of the initial search terms, where "MyAlertName" is literally the alert name:
What does it mean? It doesn't seem to make any difference if it's there or not, but the searches do work with it present, apparently it is syntactically correct.
The docs I've found relating to double-colon syntax don't seem to describe anything like this, and "host" in our environment is always a server name.
