Match_type with tolerance: abbreviations , rivers, ... in addresses

Dear ors-community,

I am trying to geocode the following address ‘Gutenbergstr. 3, Hatzfeld (Eder)’
The first entry in the JSON response has he following properties:
“label”: “Gutenbergstra\u00dfe 3, Hatzfeld, HE, Germany”,
“layer”: “address”,
“localadmin”: “Hatzfeld (Eder)”,
“localadmin_gid”: “whosonfirst:localadmin:1377684985”,
“locality”: “Hatzfeld”,
“locality_gid”: “whosonfirst:locality:101810103”,
“macrocounty”: “Kassel Government Region”,
“macrocounty_gid”: “whosonfirst:macrocounty:404227551”,
“match_type”: “fallback”,

I wonder why the match_type is not stated as being ‚exact‘

Any on preprocessing of addresses would be welcome.

Rolf
