Hi,  
My error log contains lines like:

> exception 'RedisException' with message '127.0.0.1:13635 connection closed'

The log field in not\_analyzed and I'm trying to match the IP and the port using a simple regex but I'm not getting any match.  
The regex filter is

> message:"._'127.0.0.1:[0-9]+ ._"  
> message:"._'127\.0\.0\.1:[0-9]+ ._"

What am I doing wrong here ? I'm using ES 1.6 with Kibana 4.1.1

According to the [query string documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html#_regular_expressions) the regexp must be surrounded by forward slashes. I believe this will work:

message:/.'127.0.0.1:[0-9]+ ./

That said, I think you should use Logstash to parse these strings and extract the information you're interested in to separate fields.
