Hello
I have one  question about search in Virtuemart 2.0

IF In a database produkt_name =" Номер по каталогу   4301-2204043"
                                                    ("Number under the catalogue 4301-2204043")

If I input in  search field value  4301-2204043  that occurs of nothing in general
And in navigation term there is a following

Вы здесь: Главная> Продукция> 4301           
                                      (You here: Main> Production> 4301)

If value of a field produkt_name=" Номер по каталогу   43012204043"
                                                     "Number under the catalogue 43012204043")
without a symbol ' - '

That search works normally
Why?

Before I used version VM 1.14 there all worked correctly
