Как реализовать нестрогий поиск на php?
$search_text = 'лист';

array_filter($array, function($el) use ($search_text) {
        return ( strpos($el['text'], $search_text) !== false );
    });

require_once 'vendor/autoload.php';

$fuse = new \Fuse\Fuse([
  [
    "title" => "Old Man's War",
    "author" => "John Scalzi"
  ],
  [
    "title" => "The Lock Artist",
    "author" => "Steve Hamilton"
  ],
  [
    "title" => "HTML5",
    "author" => "Remy Sharp"
  ],
  [
    "title" => "Right Ho Jeeves",
    "author" => "P.D Woodhouse"
  ],
], [
  "keys" => [ "title", "author" ],
]);

$fuse->search('hamil');

/*
Array
(
  [0] => Array
    (
      [title] => The Lock Artist
      [author] => Steve Hamilton
    )
  [1] => Array
    (
      [title] => HTML5
      [author] => Remy Sharp
    )
)
*/
