Hi, Please help,

I have been struggling with this for a few days.

How can I match a numeric field against a long list of numbers?  
Would it be best to use grok or ruby?

I can do it for one but there must be a more elegant way than this.  
My match list is non linear so I cannot use greater than or any of the other operators.

if [filed] == 9991 {  
...  
} else if [field] == 5678 {  
...  
}  
} else if [field] == 91011 {  
...  
}  
} else if [field] == 121314 {  
...  
} else {  
...  
}

Try this

```auto
if [field] in [9991, 5678, 91011, 121314] {
    ...
}
else {
    ...
}
```

Custom Ruby code is also an option, and could be a better alternative depending on what you want to do when the value matches. If you are going to use Ruby inside the _if_ branch to manipulate numbers, it may make sense to also have the actual check inside the Ruby block.

Thank you PAZ!  
That seems to be working well.

Thought I tried that but must have been  
if [field] == [##,##,##]
