Problematic behavior with street names that start with a number (when this number is also one of its housenumbers)

[AdrienVH-c2c]

Hi !

I would love to have some feedback from users about dealing with street names that start with a number, when this number is also a housenumber of this street. We have a lot of cases in France, especially when it comes to dates or military references...

Let's have an example...

About the "Rue du 8 Mai 1945" in Nevers (France)...

If I'm searching "12 rue 8 mai 1945"

https://api-adresse.data.gouv.fr/search/?q=12+rue+8+mai+1945&citycode=58194

I get the good result ✅ : 12 Rue du 8 Mai 1945 58000 Nevers (housenumber 58194_2820_00012)

If I'm searching "rue 8 mai 1945"

https://api-adresse.data.gouv.fr/search/?q=rue+8+mai+1945&citycode=58194

I get the good result ✅ : Rue du 8 Mai 1945 58000 Nevers (street 58194_2820)

if I'm searching "8 mai 1945"

https://api-adresse.data.gouv.fr/search/?q=8+mai+1945&citycode=58194

I get the wrong result ❌ : 8 Rue du 8 Mai 1945 58000 Nevers (housenumber 58194_2820_00008)

It's definitely related to tokenization.
There is no fallback on "street mode".
