This commit changes the event snippet tag option which was misconfigured. Using the option fakem2m is indeed the way to go to filter the events based on the given tags. This commit also changes the way the domain works with tags: tags from the same category will apply an OR condition between them and tags from a different category will apply an AND condition.
