Here is an example to remove a single field:
|
||
|
||
```js
|
||
{
|
||
"remove": {
|
||
"field": "user_agent"
|
||
}
|
||
}
|
||
```
|
||
|
||
To remove multiple fields, you can use the following query:
|
||
|
||
```js
|
||
{
|
||
"remove": {
|
||
"field": ["user_agent", "url"]
|
||
}
|
||
}
|
||
```
|
||
|
||
You can also choose to remove all fields other than a specified list:
|
||
|
||
```js
|
||
{
|
||
"remove": {
|
||
"keep": ["url"]
|
||
}
|
||
}
|
||
```
