Bonjour,  
J'aimerais savoir si avec FSCrawler, y'a un moment de paramétrer le nombre de réplica parce que j'ai constaté qu'on peut paramétrer le nombre de shard dans les settings.

Oui. Voici par exemple comment faire: [https://fscrawler.readthedocs.io/en/latest/admin/fs/elasticsearch.html#creating-your-own-mapping-analyzers](https://fscrawler.readthedocs.io/en/latest/admin/fs/elasticsearch.html#creating-your-own-mapping-analyzers)

Merci à vous pour vos retours.  
J'ai déjà eu a refaire mon propre mapping, number\_of\_shards m'a permis de pouvoir augmenter mon nombre de shards à 3.  
Mais pour le nombre de replica, je suis toujours pas arrivé à cerner comment modifier le fichier \_setttings.json pour le redéfinir.

</div>

je passe finalement par kibana pour modifier mon nombre de shards et de replica comme suit :

````auto
PUT nom_index
{
    "settings" : {
        "index" : {
            "number_of_shards" : 3, 
            "number_of_replicas" : 3
        }
    }
}```  

Et dans mon fichier .fscrawler/_default/6/_settings.json j'ai juste défini "number_of_shards": 3,
Mais après une dizaine de fichier indexés(exactement 70 fichiers ), je me retrouve avec cette erreur 

```14:34:57,282 e[33mWARN e[m [f.p.e.c.f.FsParserAbstract] Can't find stored field name to check existing filenames in path [/tmp/es]. Please set store: true on field [file.filename]

Merci à vous de me dire où se situe mon erreur

Tu n'as pas repris certains éléments imposés quand tu as fait ton mapping personnalisé.  
Il faut que tu prennes un mapping type et que tu l'ajustes sans pour autant enlever les champs nécessaires.
