Hello, I have log lines that may report key:value pair out of order.

2016-06-01 08:52:52 [info]: key1:value1, key2:value2  
2016-06-01 08:52:52 [info]: key3:value3, key2:value2  
2016-06-01 08:52:52 [info]: key2:value2, key1:value1, key3:value3

I can find key:value pairs using below grok pattern a) if they appear in right order b)and they are for sure present  
%{TIMESTAMP\_ISO8601:timestamp} [%{WORD:logLEVEL}]: key1:%{WORD:value1}, key2:%{WORD:value2}

I want to be able to capture out of order and optionally skup some fields as well. As a result, I would like to create following object.

Line#1  
{  
"timeStamp": "2016-06-01 08:52:52",  
"logLEVEL":"info",

//all key value pairs mentioned  
"key1":"value1",  
"key2":"value2"  
}

Line#2  
{  
"timeStamp": "2016-06-01 08:52:52",  
"logLEVEL":"info",

//all key value pairs mentioned  
"key3":"value3",  
"key2":"value2"  
}

Line#3  
{  
"timeStamp": "2016-06-01 08:52:52",  
"logLEVEL":"info",

//all key value pairs mentioned  
"key1":"value1",  
"key2":"value2",  
"key3":"value3"  
}

Have you considered using the [kv](https://www.elastic.co/guide/en/logstash/current/plugins-filters-kv.html) filter instead of direct grok? It should do what you're trying to do.
