I have a documents see example ```auto "message":"Syslog connection established; fd='15', server='AF_INET(111.103.111.65:1514)', local='AF_INET(0.0.0.0:0)'" "message":"Syslog connection established; fd='14', server='AF_INET(222.103.111.65:1514)', local='AF_INET(0.0.0.0:0)'" "message":"Syslog connection established; fd='15', server='AF_INET(333.228.333.64:1514)', local='AF_INET(0.0.0.0:0)'" "message":"Syslog connection established; fd='14', server='AF_INET(444.444.333.64:1514)', local='AF_INET(0.0.0.0:0)'" "message":"[0x00001111] [WEBCONSOLE] >> Error: CONSOLE ERROR ERROR TypeError: null is not an object" "message":"[0x00002222] [WEBCONSOLE] >> Error: CONSOLE ERROR ERROR TypeError: null is not an object" ``` and I want to aggregate similar documents ```auto 4 "message":"Syslog connection established...." 2 "message":"...CONSOLE ERROR ERROR TypeError...." ``` The intention is to do frequency analysis of syslog messages I want to identify the most repeated messages in the dataset the problem is I cant aggregate by term keyword message because if the line differs IP address it is not aggregated together. I did it by filter aggregation but it has to be done manually but it is time consuming and I feel I miss many important messages. ```auto "message":"*Syslog connection established*" ``` the dataset is huge 600k documents/sec I am looking for some kind of function group by messages with 70% similar words in it. thank you ---
