elasticsearch wildcard查询大小写敏感问题解决

先给以前的index加上别名，并且程序里面也修改一下查询index_execution改为查询index_execution_active

curl -XPUT http://15.99.72.167:9200/index_execution/_alias/index_execution_active

然后新建一个索引，如下所示，其中最关键的是新增了标红的部分的normalizer   这是taskcode和tasktitle这2个字段能够不区分大小写的关键

curl -XDELETE http://15.99.72.167:9200/index_execution_20200414

curl -XPUT http://15.99.72.167:9200/index_execution_20200414 -d '
{

"index": {
"number_of_shards": "5",
"number_of_replicas": "0"

"analysis": {
"normalizer": {

"filter": [
"lowercase"
]
}
}
}
}

}

curl -XPUT http://15.99.72.167:9200/index_execution_20200414/_mapping/type_execution?pretty -d '{

}'

建好新的索引后，用postman或者curl 进行_reindex 操作

curl -XPOST http://15.99.72.167:9200/_reindex -d '

{
"source": {
"index": "index_execution"
},
"dest": {
"index": "index_execution_20200414"
}
}

'

等新索引reindex完成后，通过alias把使用的索引切换到新建的不区分大小写的 index_execution_20200414   上，完成不区分大小写的问题解决

curl -XPOST http://15.99.72.167:9200/_aliases -d '

{
"actions": [
{ "remove": { "index": "index_execution", "alias": "index_execution_active" }},
{ "add": { "index": "index_execution_20200414", "alias": "index_execution_active" }}
]
}
