## 简述

此过滤器可以过滤省略元音。如，"l’avion" (the plane)  将会被过滤成 "avion" (plane)。

支持articles参数，其值为一组stop words（停止词，没有实际含义可忽略的词）。如下例所示：

```
"index" : {
    "analysis" : {
        "analyzer" : {
            "default" : {
                "tokenizer" : "standard",
                "filter" : ["standard", "elision"]
            }
        },
        "filter" : {
            "elision" : {
                "type" : "elision",
                "articles" : ["l", "m", "t", "qu", "n", "s", "j"]
            }
        }
    }
}

```
