И покликайте по выдаче

Некоторые сайты падают в 400 ошибку из-за слишком длинного реферера.

Но из Гугла и мейл.ру такого нет с этими же сайтами !

Потому что (очевидно) у гугла и мейл.ру не такой длинный реферер.

Разумно - не подумал :)

Значит они запрос больше чем Яндекс обрезают.

Тогда другой вопрос- у меня сайт вот тоже не откликается по таким длинным запросам - с этим надо бороться или нет ?

Не думаю что кто-то ищет запросы длиной более 4-5 слов
