Search…

By default the plugin allows searching any character without restriction. If you however need to replace (or remove) certain special characters, use the code below.
​What is this, and where do I put this custom code?​
add_filter('asp_search_phrase_before_cleaning', 'asp_replace_characters', 10, 1);
add_filter('asp_query_args', 'asp_replace_characters', 10, 1);
​
function asp_replace_characters( $s ) {
  $characters = "',._-?!"; // Type characters one after another
  $replace_with = ' ';     // Replace them with this (space by default)
​
  if ( is_array($s) ) {
    if ( isset($s['s']) && !$s['_ajax_search'] ) 
      $s['s'] = str_replace(str_split($characters), $replace_with, $s['s']);      
  } else {
    $s = str_replace(str_split($characters), $replace_with, $s);
  }
​
  return $s; 
}
Type the characters into the $characters variable, one after another. By default it replaces it with a space character. In case you want to remove those characters, change the
$replace_with = ' ';
with:
$replace_with = '';

Replace search keywords (whole words)
