How to search for an exact match

GravityView's current search functionality doesn't use an exact match, it uses the contains operator, so if you search for the word "Kansas", results containing that word, like "Arkansas", will also show up:

If you wish to change the search functionality to look for an exact match, then you need the function below:

add_filter( 'gravityview_search_operator', function( $operator, $filter = array() ){

	$run_on_views = [100,200]; //The IDs of the Views you'd like to affect [100,200,...]

	if ( ! class_exists( '\GravityView_View_Data' ) ) {
		return $operator;
	}
	$views  = \GravityView_View_Data::getInstance()->views->all();
	if(sizeof($views)){
		foreach ( $views as $view ) {
			if( in_array( $view->ID, $run_on_views ) ){
				$operator = 'is';
			}
		}		
	}
	return $operator;
	
}, 10, 2);

Here's the result:

Searching with empty values

If you have more than two fields on your Search Bar and leave one empty, the search will return the same results as before:

But if you want to require users to fill all fields for results to appear, then you'll need also to add this other code snippet below:

// This disallows empty field values
add_filter( 'gravityview/search/ignore-empty-values', function() {
	return false;
});

This way, the search won't return any results until both fields are filled:

This is perfect for restricting entry results to only those users that know particular details from their submission, like an SSN number in conjunction with a Zip Code or date of birth.

Defining strict matches for particular fields

If you need to target just a specific field from a specific form, then the code is a little bit more complex. To achieve that, we've created a simple plugin you can download here. You'll need to modify the Form ID and Field IDs inside that plugin's code using the plugin editor on your WordPress Dashboard:
