Description de l'erreur

Bonjour,

J'utilise l'api de géocodage depuis peu.
Plusieurs utilisateurs nous ont remonté que des résultats ne remontaient pas

Quand ont tape "20 boulevard Mat"
Aucun résultat cohérent ne remonte. Les utilisateurs cherchent à trouver l'adresse "20 boulevard matabiau"

Par contre quand on tape "20 boulevard mata", ça remonte bien.

Bonjour @pYassine et merci pour ce signalement.

Je constate que le comportement s'observe aussi sur l'API Adresse :
https://api-adresse.data.gouv.fr/search?q=20%20boulevard%20Mat

Cela est lié au mécanisme d'auto-complétion dans le moteur addok. Il semble ici que le terme mat soit réduit à ma à l'étage de tokenisation, terme ensuite trop court pour être utilisé pour l'auto-complétion qui se déclenche à 3 caractères.

Je vais créer un ticket sur le moteur en question.
