I have a random log file which contain diff data, I have created fields in it using mutate filter, my if conditions are working but not my else conditions working.
log line : 90-50-31: ill ill you are You
if [ty] =~ "YOU" or "you" {
mutate {
gsub =\> ["field", "[a-zA-Z]+" , "" ]
}
} else {
mutate { gsub =\> ["field", "[0-9]+" , "" ] }
}
not any else is working, drop filter in else drops every thing and my data for next field becomes invisible

every thing is working fine except any else statement, or give em any else working statement with conf file other than drop filter to get an idea

I would expect to get an error for that. If you want to match either YOU or you then you can use
```
if [ty] =~ /YOU|you/ {
```
If you want it to be case insensitive you can use
```
if [message] =~ /(?i:foo)/ {
```
