The Search stats section in the plugin panel is where you can find all the statistics related to the Top searches (the most popular searches), Top clicked products (the products with the most clicks from the search results), and Searches with no results (the searched made by users that produced no results).
If you need to monitor statistics for a specific time interval, you can use the Filter by date option.
To reset the filter, click on the Reset button.
At the bottom of each statistic, you will find a ‘View all‘ link that allows you to access the table showing each query/product and its number of searches/clicks. From this table, you can also filter the statistic by date.
