  +Options that control how Filebeat deals with log messages that span multiple lines. Multiline messages are common in files that contain Java stack traces. 
   
   The following example shows how to configure Filebeat to handle a multiline message where the first line of the message begins with a bracket (`[`). 
   
  
positive.code: 
  -------------------------------------------------------------------------------------
  
  Filebeat takes all the lines that do not start with `[` and combines them with the previous line that does. You can use this configuration to handle a Java stack trace that contains multiline messages like:
  
  ["source","sh",subs="attributes,callouts"]
  -------------------------------------------------------------------------------------
  
negative.code: include_lines: ["^ERR", "^WARN"]
  -------------------------------------------------------------------------------------
  
  NOTE: If both `include_lines` and `exclude_lines` are defined, Filebeat executes `include_lines` first and then executes `exclude_lines`. So, for example, to export all Apache log lines except the debugging messages (DBGs), you can use:
  
  [source,yaml]
