Differentiate between auto search and manual search

In class-frontend.php, the store_search method fires the wpsl_store_search action. I’m working on an integration for the WordPress plugin Independent Analytics and started using this hook to track form submissions.

While this hook fires for manual searches, I also noticed that it fires for those automatic searches that trigger on page load.

I was hoping to get a new argument added to the hook to allow us to differentiate between the two. Something like this works real well in testing:

// Before
do_action( 'wpsl_store_search' );

// After
$is_autoloaded = isset( $_GET['autoload'] ) && $_GET['autoload'];
do_action( 'wpsl_store_search', $is_autoloaded );

Another option could be firing different hooks based on what happened:

// Before
do_action( 'wpsl_store_search' );

// After
$is_autoloaded = isset( $_GET['autoload'] ) && $_GET['autoload'];
do_action( $is_autoloaded ? 'wpsl_store_search_autoload' : 'wpsl_store_search' );

Thanks for considering the request. Let me know what you think!
