ES7 _doc报错

在使用ES7设置mapping的时候，发现报错如下：

0x02 解决
es从6跨越到7，还是有些变化的；在es7中已经在内部取消了_doc这类type；
把上面的语句中删除_doc就行了，改成如下：
PUT my_index
"settings":
"analysis":
"char_filter":
"my_char_filter":
"type": "mapping",
"mappings": [
", => "
]
,
"filter":
"my_synonym_filter":
"type": "synonym",
"expand": true,
"synonyms": [
"lileilei => leileili",
"hanmeimei => meimeihan"
]
,
"analyzer":
"my_analyzer":
"tokenizer": "my_tokenizer",
"char_filter": [
"my_char_filter"
],
"filter": [
"my_synonym_filter"
]
,
"tokenizer":
"my_tokenizer":
"type": "pattern",
"pattern": "\\\\;"
,
"mappings":
"properties":
"text":
"type": "text",
"analyzer": "my_analyzer"
