hi, i want to extracted the first word from each variable the index has a field called search_name which has these variables:

 

Risk - 24 Hour Risk Threshold Exceeded - Rule
Endpoint - machine with possible malware - fffff
Network - Possible SQL injection - Rule

 

i want to perform a regex to extracted the first word out of each variable so the output would be:

 

risk

endpoint

network

 

 

 

 

thanks ^_^

And as you want those with lower cases then add this

| makeresults
| eval _raw ="Risk - 24 Hour Risk Threshold Exceeded - Rule
Endpoint - machine with possible malware - fffff
Network - Possible SQL injection - Rule"
| multikv noheader=t 
``` Above create test data ```
| rex "^(?<result>\w+)"
| eval res = lower(result)
| table res result _raw
