New to elasticsearch and still getting to grips with everything!
I've imported a load of nmap xml results in to elastic search using the VulntoES (https://github.com/ChrisRimondi/VulntoES)
This has worked well and I can see all the data under discover. When I come to visualise a field such as IP with Graph, I get the following error: Fielddata is disabled on text fields by default.
I have searched under in the documentation and see see that I need to add Set fielddata=true on.
How do I update the data in my index nmap-vuln-to-es ?
EDIT: I am using ELK v5.2 on ubuntu 16
