Hi!
1. These are the phrases that your users have entered into the live search and triggered the live search. If you see those, that means those phrases were actually used, even if they don’t make any sense. Those are no errors though, that is what has been entered into the search bar for sure – the plugin only stores them.
2. I’m not an expert with analytics, but generally you want to see reports within the Engagement -> Events panel. Then click on the search_end event. Then on the Event Category and Event Label panels you can see all the defined values from the back-end.
Typically Event Label is used as the search phrase, in my example the results count is also included. If you only want the search phrase, then you can change it: https://i.imgur.com/DzfYOTd.png
Again, I’m no expert, but as far as I know google analytics is very versatile and you can basically generate all kinds of reports and even download them.
