I don't understand this.
On the main page i found a "search 9" with the same rule:
"Additionally, each arrow points to the 9 in the respective row or column. The number in the cell with the arrow is the distance from the cell to the 9 in this row or column."
But in your picture both r8c13 point to a given 7 in r8c2.
Also it cannot be meant, that you continue counting on the other side of the row/column (in opposite direction) or that the arrow cell could be 9.
Nothing possible in row 8, is it ?
[Added:] After i had a look at that one, i can understand your original question.
I marked all cells, which cannot be 9, and pencilmarked all cells with less than 4 candidates - no chance, i cannot imagine, that there are friendly techniques, which can be used to solve it in reasonable time.
