I have a csv file, with data like this :

field1;field2;field3,field4\_1::field4\_2::field4\_3;field5;field6

The 4th field is composed of 3 values that I want to divide into 3 different fields in Elasticsearch.

Is there a way to do so?

Thanks.

Have a look at the dissect filter to see if it does what you require - [Dissect filter plugin | Logstash Reference [7.15] | Elastic](https://www.elastic.co/guide/en/logstash/current/plugins-filters-dissect.html)

It's good I managed to do it with some Ruby and the split from mutate filter 🙂

Have a nice day and thanks for the answer!
