Ajouter / Supprimer un document ElasticSearch

Pour insérer un document on utilise la commande POST Exemple:

POST /protic_test/measures
{"test":"tutu"}

Avec cette méthode le document est stocké dans la base, Elastic génère automatiquement un ID.

Cela peut poser un probléme lorsque nous avons un document avec notre propre ID déjà défini, dans ce cas voir la méthode PUT.

Pour vérifier, on fait une recherche sur tous les documents dont “test”=“tutu”

POST /protic_test/measures/_search
{
  "query":{
    "match":{
      "test":"tutu"
    }
  }
}
