• “sport/#” also matches the singular “sport”, since # includes the parent level.

• “sport/tennis/#” is valid
• “sport/tennis#” is not valid
• “sport/tennis/#/ranking” is not valid
The plus sign (‘+’ U+002B) is a wildcard character that matches only one topic level. The single-level
wildcard can be used at any level in the topic filter, including first and last levels. Where it is used it must
occupy an entire level of the filter [MQTT-4.7.1-3]. It can be used at more than one level in the topic filter
and can be used in conjunction with the multilevel wildcard.
For example, “sport/tennis/+” matches “sport/tennis/player1” and “sport/tennis/player2”, but not
“sport/tennis/player1/ranking”. Also, because the single-level wildcard matches only a single level,
“sport/+” does not match “sport” but it does match “sport/”.
• “+” is valid
• “+/tennis/#” is valid
• “sport+” is not valid
• “sport/+/player1” is valid
• “/finance” matches “+/+” and “/+”, but not “+”
