i have this query

GET product_de/_search
{
              "from" : "0","size":"5",
                  "query": {
                      "match": {
                        "product_title.edgengram": "34151001 "
                      }
                    }
                 }

I always get first products with title that contains 34151003 .. 34151003 and then 34151001 in title.
