Hi, Is it possible using props.conf and transforms.conf to route some data on an index based on the source field? Let's say index1 contains a lot of sources, in some sources it contains certain words in the path for example (source="*dev-ksm*" OR source="*int-ksm*" OR source="*qa-ksm*" OR source="*amq-*-ksm*") For this scenario I'd like to route events that their source contains the above matching sources to an index2 Was thinking in something like this: props.conf [index::current_index] TRANSFORMS-routing=filter-to-new_index   transforms.conf [filter-to-new_index] DEST_KEY = _MetaData:Index SOURCE_KEY = MetaData:Source REGEX = (?i)(.*dev-ksm.*|.*int-ksm.*|.*qa-ksm.*|.*amq-.*-ksm.*) FORMAT = new_index   Does not seem to be currently working. Hence the question if its possible to do something like this.   Thanks in advance.     ... View more
