ElasticSearch Mise en surbrillance échoue sur les requêtes de correspondance avec l'index avec Ngram Analyzer

Question

J'ai créé un index avec ngram analyseur défini sur tous les champs de l'index et _all personnalisé. Après l'indexation de quelques documents, j'essaie d'interroger l'index pour avoir une suggestion comme caractéristique.

La sortie de la requête renvoie des résultats mais ils ne sont pas mis en surbrillance.

Answer 1

j'ai pu obtenir les résultats en mettant term_vector dans le schéma.
