Accessing Relevanssi User Searches programatically

relevanssi_date_queries( $days, $title, $version ) generates the HTML code for the display. $days is the number of days of results to show, $title is the element heading and $version is either good for hits or bad for misses.

This echoes out the results, so if you want to use it for something else, you need to capture it with an output buffer:

ob_start();
relevanssi_date_queries( 7, 'title', 'good' );
$content = ob_get_contents();
ob_end_clean();

Now you have the most common queries for the past 7 days in $content. It’s a HTML table formatted for the User searches page, so you may need to clean it up a bit.
