Configuration Analyzer ElasticaBundle

Bonjour,

J'essaie, tant bien que mal, de configurer mon analyzer pour ElasticSearch avec ElastiaBundle.
Mais j'ai l'impression que celui-ci n'est pas pris en compte.

Voici la configuration :

fos_elastica:
    indexes:
        app:
            client: default
            settings:
                  analysis:
                    analyzer:
                      custom_analyzer :
                        type     :    custom
                        tokenizer:    nGram
                        filter   :    [my_stopwords, asciifolding ,lowercase, snowball, my_elision, worddelimiter]
                      custom_search_analyzer :
                        type     :    custom
                        tokenizer:    standard
                        filter   :    [my_stopwords, asciifolding ,lowercase, snowball, my_elision, worddelimiter]
                    filter:
                      snowball:
                        type:     snowball
                        language: French
                      my_elision:
                        type:     elision
                        articles: ["l", "m", "t", "qu", "n", "s", "j", "d"]
                      my_stopwords:
                        type:      stop
                        stopwords: [_french_]
                        ignore_case : true
                      worddelimiter :
                        type:      word_delimiter

Et voici un de mes mappings :

##### Document #####
                Document:
                    mappings: 
                        id: ~
                        title:
                            index_analyzer: custom_analyzer
                            search_analyzer : custom_search_analyzer
                        resume:
                            index_analyzer: custom_analyzer
                            search_analyzer : custom_search_analyzer
                        date: ~
                        documentType:   
                            type: object
                            properties:
                                id: ~
                                name: ~
                        files:
                            type: object
                            properties:
                                id: ~
                                name: ~
                                path : ~
                    persistence:
                        driver: orm
                        model:  ManageBundle\Entity\Document
                        repository: ManageBundle\RepositoryElastica\DocumentRepositoryElastica
                        provider: ~
                        listener: ~
                        finder: ~
