You'll want use a regular expression for this. Something close to this should work:

```auto
def m = /opt\/apps\/logs\/([a-z\-]+)\/([a-z\-]+)\/.*/.matcher(doc['my_field_name'].value)

return m.group(1) + m.group(2)

```

See [the Matcher docs](https://docs.oracle.com/javase/8/docs/api/java/util/regex/Matcher.html) for more information on how to use this class.
