How to use rex max_match resulting in only unique values

Hello,

 

I am trying to get a list of values using max_match=5.  However I need the results to only return unique values and not just list 5 values regardless of them being duplicates.

| rex max_match=5 (?P<BrandID>(202\d.+?))\"

|table BrandID

Your help and energy is greatly appreciated.  🙂

Thank you,

Spencer Neal

That's not what rex does.  It just matches patterns.  If you need unique results, then insert the mvdedup function into your query.

```Get all BrandID values```
| rex max_match=0 (?P<BrandID>(202\d.+?))\"
```Filter out duplicate values ```
| eval BrandID=mvdedup(BrandID)
```Keep only the first 5 unique values```
| eval BrandID=mvindex(BrandID, 0 4)
| table BrandID
