我尝试配置ElasticSearch：

fos_elastica:
indexes:
    test:
        settings:
            index:
               analysis:
                   analyzer:
                       autocomplete:
                           type: custom
                           tokenizer: lowercase
                           filter   : [my_ngram]
               filter:
                   my_ngram:
                   type: "nGram"
                   min_gram: 2
                   max_gram: 20
        types:
            Track:
                mappings: 
                    title: { analyzer: autocomplete }
                    artist: { analyzer: autocomplete }
                persistence:
                    driver: orm
                    model:  Website\TestBundle\Entity\Track
                    provider: ~
                    listener: ~
                    finder: ~

这是我执行“
http://mydomain.com:9200/test/_analyze?analyzer=autocomplete&text=rih
” 时的错误

{"error":"ElasticSearchIllegalArgumentException[failed to find analyzer [autocomplete]]","status":400}

有什么问题 ？谢谢
