search function will be back to speed when i fully recode it and rebuilt search index, and i plan to do this within 10 or 15 days. As soon as it will be done, you will notice a huge difference

as Chip says, i needed to block some single words as some users where searching for "car", "ford", "lol", "mp3" and all those silly words that created huge load for nothing. That's why i did this at first... but will soon be back to how it should be
