Hi,

My setup:  
Kibana 5.6.2  
ES 5.6.2

Need some help to extract the SIM number from the path field in a document  
The field value:

`C:/HWM/Apps/CAR/Export/971XXXXXX231_20180903.CSV`

I need to fetch only the value **971XXXXXX231** as a result for the below mentioned scripted field.

Here is my attempt using the examples mentioned in [scripted help](https://www.elastic.co/blog/using-painless-kibana-scripted-fields)

```
def logger= doc['path.keyword'].value;
if (logger!= null) {
    int lastSlashIndex = logger.lastIndexOf('/');
    if (lastSlashIndex > 0) {
    return logger.substring(lastSlashIndex+1);
    }
}
return "";

```

But the result is 971XXXXXX231\_20180903.CSV

Fixed it myself.

```
def logger= doc['path.keyword'].value;
if (logger!= null) {
    int lastSlashIndex = logger.lastIndexOf('/');
    int lastUndrIndex = logger.lastIndexOf('_');
    if (lastSlashIndex > 0) {
    return logger.substring(lastSlashIndex+1,lastUndrIndex);
    }
}
return "";
```
