This search uses the OR Boolean operator to search for events in either index=netfw with "failure" in it or in index=netops with "warn" or "critical" in it. The parentheses ensure that the warn and critical criteria are grouped together and only apply to the index=netops part of the search.
The other options do not correctly group the criteria or use the AND operator incorrectly, which would not return the desired results.
