FileBeat Log Message combine

I am looking for a way (in FileBeat if possible) to combine log messages that are timestamped at the same time.
For example, I have an error log message with 9 lines. If I search for a certain word in the log via Kibana, it flags the log without a problem.
However, the rest of the error log message lines are not displayed because it doesn't satisfy the search criteria - but it is part of the same error log message.
Looks like elasticsearch is treating each line in the error message as a separate message line.
How can I combine the lines in the same error log message - so I can display the error message as one complete message?


So i've found something called "View Surrounding Documents" in Kibana which enables me to do something similar. But is there any way to combine the message in the logging area?
