A problem with using /w in regular expression filter

[idit gawiser 2]

We are trying to use /w in regular expression filter in Tibco 5.11. But, this expression does not allow an underscore, in contrast with the documentation (https://docs.tibco.com/pub/logeva/6.2.0/doc/html/GUID-4559E750-58B5-4CC1...)

 

Did you encounter this behavior Is there other way to use /w in Tibco regular expression filter

 

Thanks
