My multiline message shows only one line in Kibana Discover

I use filebeats multiline input to push a java exception log to elasticsearch. But when I look up them in my Kibana Discover view, they are just shown in a single line, which means it erased all LFs in my text. Can anyone give me some suggests?
The message a shown normally in the origin doc, but not work in the table.
