Hi – great question!
It’s certainly possible to set the plugin to only display the first upcoming instance of a set of recurring events – and this should be respected where a search takes place in the main list view of events. By design, this is not necessarily the case in month view where that wouldn’t make as much sense.
The only real caveat then is that if a basic WordPress search is conducted you may see multiple instances of the same event in the search results – however, our plugins and of course WordPress itself are customizable that you could certainly workaround this.
I hope that answers your questions, but please just let me know if we can assist with anything else 🙂
