Search comma surrounded phrase in _raw using rex

sai_shreyashi_p — Mon, 09 Sep 2019 06:26:10 GMT

In the logged data:

....,en,us,....(one record)
....,en,in,.....(another record)
(Here .... represents string data)

I need to extract 'us' and 'in' from _raw from each log.
rex field = _raw "(?:us?[^,]+)"

This is erroneous but it will be great if someone can help out.

actually in the data it isn't necessary for the country to be preceded by 'en' which is why I was facing issues.
Is there any way to look for strings like ",us," or ",jp,"? Regex or rex expression for looking in _raw?

Sorry for the vague description of data but actually this data cannot be exposed.
They are mainly comma separated values in the middle of which we have language code,country code.
They are somewhere in the middle of _raw.
Ex: 324724588,nhiden-niuen-jkjl,en,us,6484-47934......,...

If the sample data above is accurate then this should work:

... | rex ",(?<lang>\w+),(?<country>\w+)"
