doc['field'].value 从不返回值
doc['field'].value never returning values
使用 Kibana/Elasticsearch 版本 6.6。
正在尝试 运行 下面简单的无痛脚本:
String val = "Vanished";
if(doc.containsKey('type')) {
return doc['type'].value;
}
return val;
在 Preview Results
部分,当我尝试 运行 代码时,First 10 results
部分总是:
[]
但是,如果我像下面这样更改代码:
String val = "Vanished";
if(doc.containsKey('type')) {
return "Present";
}
return val;
我在同一 Preview Results
部分得到以下结果:
[
{
"_id": "Kha1NmkBcY4KotEKXsZz",
"test112": [
"Present"
]
},
{
"_id": "1oS1NmkBjBc6pl9UX0IW",
"test112": [
"Present"
]
},
{

]
},
{
"_id": "yRC1NmkBCa8dRNQVZTFf",
"test112": [
"Present"
]
}
]
有人可以帮忙找出 doc['type'].value
失败的原因吗?
此问题已通过将脚本更改为以下内容得到解决:
String val = "Vanished";
if(doc.containsKey('type.keyword')) {
return doc['type.keyword'].value;
}
return val;
请注意使用 type.keyword
而不是 type
作为字段名称。
