I am seeing `<empty search>` as the most popular search in analytics. How can I avoid this behavior in Magento?

Modify the search function using the 'beforeInstantsearchInit' custom event. 

The new function should include a condition that checks to see if there is a query populated, if not, analytics is set to false.

 

For example:

const search = instantsearch({
   appId: 'XXX',
   apiKey: 'XXX',
   indexName: 'XXX',
   searchFunction: function(helper) {
      if (helper.state.query === '') {
         helper.setQueryParameter('analytics', false).search();
      } else {
         helper.search();
      }
   },
});
