We are having a difficult time trying to explain certain score obtain when requesting the Rest World Geocoding Service. Anyone can help us out?

We are looking for the "rue Notre-Dame" [in the province of Quebec] and when launching this request:

https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates?SingleLine=rue%20Notre-da%20&f=pjson&distance=50000&location=-75,45&countryCode=CA&maxLocations=6

 

We are obtaining :

 

"candidates": [   {    "address": "Rue du passage, Grand-Mère, Shawinigan, Québec, G9T",    "location": {     "x": -72.687233532632504,     "y": 46.604699724003538    },    "score": 89.400000000000006,    "attributes": {         },    "extent": {     "xmin": -72.688233532632509,     "ymin": 46.60369972400354,     "xmax": -72.6862335326325,     "ymax": 46.605699724003536    }   },   {    "address": "Rue Rd, Fort McMurray, Wood Buffalo, Alberta, T9H",    "location": {     "x": -111.15360547309186,     "y": 56.660170619287101    },    "score": 93.030000000000001,    "attributes": {         },    "extent": {     "xmin": -111.15460547309186,     "ymin": 56.659170619287103,     "xmax": -111.15260547309185,     "ymax": 56.661170619287098    }   },

...

 

Even though there are many Notre-Dame streets in Quebec, the first candidate as nothing to do with "Notre-Da" and the score is 89.4!

Do you see something in our request?

How should we use the distance and the location parameters?

Any clue as why we obtain this score?

 

Cheers!
