Incrementing a string field count in Kibana
问题
在下面的查询中，likeCount 是一个字符串字段，但我需要对它执行增量操作。使用以下查询，它执行的是连接操作而不是增量操作。
POST /posts/_update/<id>
{
"script": {
"source": "ctx._source.likeCount++"
}
}
英文:
In the below query likeCount is a string field, but I need to do a increment operation on it, with the below query, it is doing a concatenation operation instead of increment.
POST /posts/_update/<id>
{
"script" : {
"source": "ctx._source.likeCount++"
}
}

你可以通过 integer.ParseInt 解析数字：
POST /posts/_update/<id>
{
"script" : {
"source": "ctx._source.likeCount = (Integer.parseInt(ctx._source.likeCount) + 1).toString()"
}
}
英文:
You can parse the number via integer.ParseInt:
POST /posts/_update/<id>
{
"script" : {
"source": "ctx._source.likeCount = (Integer.parseInt(ctx._source.likeCount) + 1).toString()"
}
}

Integer.toString worked. Making it dynamic:
POST /posts/_update/<id>
{
"script": {
"source": "ctx._source.likeCount = Integer.toString(Integer.parseInt(ctx._source.likeCount)+params.newValue);",
"lang": "painless",
"params" : {
"newValue" : 1
}
}
}
英文:
It is working with below code Integer.toString worked.
POST /posts/_update/<id>
{
"script": {
"source": "ctx._source.likeCount = Integer.toString(Integer.parseInt(ctx._source.likeCount)+1);",
"lang": "painless"
}
}
