起因：

针对A字段，既需要做分词处理，有需要做聚合统计处理，因此为这个字段配置了多个类型，index和mapping如下

index

"analysis": {
"analyzer": {
"comma_analyzer": {
"tokenizer": "comma"
},
"pinyin_analyzer": {
"tokenizer": "my_pinyin"
}
},
"tokenizer": {
"comma": {
"pattern": ",",
"type": "pattern"
},
"my_pinyin": {
"keep_none_chinese_in_first_letter": "true",
"lowercase": "true",
"first_letter": "prefix",
"keep_original": "true",
"remove_duplicated_term": "true",
"keep_first_letter": "true",
"keep_separate_first_letter": "true",
"trim_whitespace": "true",
"type": "pinyin",
"keep_none_chinese": "true",
"limit_first_letter_length": "16",
"keep_full_pinyin": "true"
}
}
}
