Hi I am using flush\_pattern in multiline to define the end of a multiline block. It is not working.

Below is my code snippet.  
_multiline { \*  
\* pattern =\> "^["_  
\* what =\> "previous"\*  
\* negate=\> true\*  
\* }\*

If I include flush pattern withing multilint scope it's throwing below error.  
[ERROR][logstash.filters.multiline] Unknown setting 'flush\_pattern' for multiline

How I can specify end of multiline block?????
