Can we use split processor with painless scripting as we can use in java or groovy?
value of RequestIntime = "ReqestIn_2017-08-21T12:10:10"
def String request = doc['RequestInTime'].value;
Seperator shoud be based on "_"(underscore).
is to possible to split
[request] = "ReqestIn"
[request] = "2017-08-21T12:10:10"
