@David-Bonner thanks for the feedback!
Regarding the errors in calculation, they just hint at locations where something might be wrong. Think about differences in mal data between OSM and HERE (as routes are generated with OSM). Also road closures, 180 degree turns etc might be a location with an error. There is nothing you can do about the errors (at this stage), they simply inform you. Ignoring them is a great idea as @Steve-Lynch said.
The search functionality will be improved in a later stage! 🙂
