Есть скрипт по поиску в базе данных но вот в чём проблема: когда идёт посик по базе )в ней существуют 4 группы ( так вот поиск должен отображать найденое по групам сначала 1 група потом 2 и так далее -а он собака отображает не по групам а по сходству с словом которое ищут!

// ====== global variables ======================

// array with search results
var results = new Array();
// search started flag
var isSearchStarted;
// Previouse search query, used to avoid search
// when getting back from some page
var prevQuery = "";
