hi,

in my case study I use these api together: **matrix** and **directions**

before making an api matrix request for N points I check if each points are reachable to the graph, I check this condition with the api **directions** and I rely on the `maximum_snapping_radius`

parameter.

If one of the N points has no routing solution with a certain `maximum_snapping_radius`

then I exclude it from the next matrix request.

I would like to know if the `matrix.maximum_search_radius`

parameter is calculated in a similar way to `directions.maximum_snapping_radius`

and if they can be set to the same value.

I thought that for right behavior `directions.maximum_snapping_radius`

it should be a little bit bigger to say `matrix.maximum_search_radius`

this is because sometimes it happens that two points are “reachable” with directions but they are not reachable by matrix
