Prestashop Search only display exactly - prestashop

Question

I am new to Prestahop 1.6 and I want to change the behaviour of the search form
Currently searching '2/05' will return '22/05', '20/5', '2/051'
Desired: '2/05' will return '2/05' ONLY if exists.

You need to overrride the find method of search class in override/classes/Search.php , here what i use on my shop :
class Search extends SearchCore {
public static function find($id_lang, $expr, $page_number = 1, $page_size = 1, $order_by = 'position', $order_way = 'desc', $ajax = false, $use_cookie = true, Context $context = null) {
if (! $context) {
$context = Context::getContext();
}
$db = Db::getInstance(_PS_USE_SQL_SLAVE_);
// TODO : smart page management
if ($page_number < 1) {
$page_number = 1;
}
if ($page_size < 1) {
$page_size = 1;
}
if (! Validate::isOrderBy($order_by) || ! Validate::isOrderWay($order_way)) {
return false;
}
$intersect_array = array();
$score_array = array();
$words = Search::extractKeyWords($expr, $id_lang, false, $context->language->iso_code);
foreach ($words as $key => $word) {
if (! empty($word) && strlen($word) >= (int) Configuration::get('PS_SEARCH_MINWORDLEN')) {
// $sql_param_search = self::getSearchParamFromWord($word);
$word = str_replace(array(
'%',
'_'
), array(
'\\%',
'\\_'
), $word);
$start_search = Configuration::get('PS_SEARCH_START') ? '%' : '';
$end_search = Configuration::get('PS_SEARCH_END') ? '' : '%';
$sql_param_search = ($word[0] == '-' ? ' \'' . $start_search . pSQL(Tools::substr($word, 1, PS_SEARCH_MAX_WORD_LENGTH)) . $end_search . '\'' : ' \'' . $start_search . pSQL(Tools::substr($word, 0, PS_SEARCH_MAX_WORD_LENGTH)) . $end_search . '\'');
$intersect_array[] = 'SELECT DISTINCT si.id_product

if ($word[0] != '-') $score_array[] = 'sw.word LIKE \'' . $start_search . pSQL(Tools::substr($word, 0, PS_SEARCH_MAX_WORD_LENGTH)) . $end_search . '\'';
} else {
unset($words[$key]);
}
}
