Regex is not working for me.

Below is my sample keys:
435948871-WH108336-1508522577814 435948936-WH350708-1508522577200
435079736-WH334548-1508522567200

I want to result only those rows which matches \d{9}(-WH350708-)\d{13}. Means result should only include '435948936-WH350708-1508522577200' row; but results into zero row.

When I user Start from operator it works (Comparison value = 435948936).

what I am doing wrong?
