Hello.  
Running that script:

`def inst = /.*instrument:([a-z]+).*/.matcher(doc['FullDetails'].value);`  
`if (inst.matches()) {`  
`return inst.group(1)`  
`} else {`  
`return "no match"`  
`}`

causes "Fielddata is disabled on text fields by default ... Alternatively use a keyword field instead."

How to solve that not doing fielddate:true?

Thanks.

I think our docs cover what to do in this:  
[https://www.elastic.co/guide/en/elasticsearch/reference/current/fielddata.html#before-enabling-fielddata](https://www.elastic.co/guide/en/elasticsearch/reference/current/fielddata.html#before-enabling-fielddata)

I found that, but I still cannot understand what should I do. Do I need to rebuild log?
