Substring Search on log message in kibana 4

Hi
I want to display only logs which i search substring

for example in my logs have message type as ERROR
if i search error, i want to display only logs which have error not entire log
how to filter in kibana 4

note : in search field i gave "astrikERRORastrik"
but it just highlighting error not filter the result..
can you help me

The search bar will filter down a set of documents, but it won't filter sections of individual documents. Is it possible for you to push one document per log line?

I would also recommend looking into something like logstash or elasticsearch ingest node to parse these log lines out into separate fields.
