I have a project on rais with searchkick and I was trying to find out if there is a way to get what people are searching the most on my site.
Is this possible with searchkick and elasticsearch?
Yes, it is possible.
Running together with searchkick you can use searchjoy gem. With searchjoy you can view and monitor the performance of your top searches.
If you don't want to use searchjoy, you can use searchkick's conversion feature. I think is not what you really want because with only conversions you will not be able to see the top searches. More information about searchkick conversions you can find at the docs.
