Hi First I have deleted the Index because its size is **30Gb**

![image](https://us1.discourse-cdn.com/elastic/original/3X/e/7/e7aebac9cf55dec868990984dd503a76d99cca50.png)

again logstash pushed the index and it is re-created, phasing this issue **illegal\_argument\_exception**

Sorted **illegal\_argument\_exception** by changing the **"fielddata" : true**

When I run the following 2 operations and set fielddata = “true”, I get the customer and the host name splits multiple.
