...when looking for a topic that consists of more than one word, it is usually better (when possible) to use the most representative one instead of the entire phrase.
A hot topic is a subject that has recently become very popular, a word or phrase used a lot more
frequently than usual. It can be seen in the chart as a peak. The topic is considered hot from the
moment it starts rising in popularity until it falls back to its old frequency level or settles
in a new one.
