}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"
}
}
}
