searchwp_lenient_accents_conversions

Using searchwp_lenient_accents you can tell SearchWP to not apply exact-match logic to words containing accented characters. Further, searchwp_leinent_accent_result allows you to override any mistakes SearchWP makes during this process by providing your own conversion result. If instead you would like to fully customize the conversion table, this hook allows you to do that.

SearchWP’s built in conversion table looks like this:

      
        <?php
      
        $conversions = array(
      
        	'À' => 'a', 'Á' => 'a', 'Â' => 'a', 'Ã' => 'a', 'Ä' => 'a', 'Å' => 'a', 'Æ' => 'a', 'à' => 'a', 'á' => 'a', 'â' => 'a', 'ã' => 'a', 'ä' => 'a', 'å' => 'a', 'æ' => 'a',
      
        	'Ò' => 'o', 'Ó' => 'o', 'Ô' => 'o', 'Õ' => 'o', 'Ö' => 'o', 'Ø' => 'o', 'ò' => 'o', 'ó' => 'o', 'ô' => 'o', 'õ' => 'o', 'ö' => 'o', 'ø' => 'o',
      
        	'È' => 'e', 'É' => 'e', 'Ê' => 'e', 'Ë' => 'e', 'è' => 'e', 'é' => 'e', 'ê' => 'e', 'ë' => 'e', 'ð' => 'e',
      
        	'Ç' => 'c', 'ç' => 'c',
      
        	'Ð' => 'd',
      
        	'Ì' => 'i', 'Í' => 'i', 'Î' => 'i', 'Ï' => 'i', 'ì' => 'i', 'í' => 'i', 'î' => 'i', 'ï' => 'i',
      
        	'Ù' => 'u', 'Ú' => 'u', 'Û' => 'u', 'Ü' => 'u', 'ù' => 'u', 'ú' => 'u', 'û' => 'u', 'ü' => 'u',
      
        	'Ñ' => 'n', 'ñ' => 'n',
      
        	'Þ' => 't',
      
        	'ß' => 's',
      
        	'ÿ' => 'y', 'ý' => 'y',
      
        	// greek
      
        	'Ά' => 'Α', 'ά' => 'α', 'Έ' => 'Ε', 'έ' => 'ε', 'Ή' => 'Η', 'ή' => 'η', 'Ί' => 'Ι', 'ί' => 'ι', 'Ό' => 'Ο', 'ό' => 'ο', 'Ύ' => 'Υ', 'ύ' => 'υ', 'Ώ' => 'Ω', 'ώ' => 'ω', 'ϊ' => 'ι', 'ϋ' => 'υ', 'Ϊ' => 'ι', 'Ϋ' => 'Υ',
      
        );

Example: to customize the accent conversion table used by SearchWP, add something like the following to your theme’s functions.php:

      
        <?php
      
        function my_searchwp_leinent_accents_conversions() {
      
        	return array(
      
        		// Only convert Greek
      
        		'Ά' => 'Α', 'ά' => 'α', 'Έ' => 'Ε', 'έ' => 'ε', 'Ή' => 'Η', 'ή' => 'η', 'Ί' => 'Ι', 'ί' => 'ι', 'Ό' => 'Ο', 'ό' => 'ο', 'Ύ' => 'Υ', 'ύ' => 'υ', 'Ώ' => 'Ω', 'ώ' => 'ω', 'ϊ' => 'ι', 'ϋ' => 'υ', 'Ϊ' => 'ι', 'Ϋ' => 'Υ',
      
        	);
      
        }
      
        add_filter( 'searchwp_leinent_accents_conversions', 'my_searchwp_leinent_accents_conversions' );
