You can easily run an aggregation to find out what they are, but what do you mean by "collect these?"

i meant i already have all my logs in the elastic search such as this example:

{  
"\_index" : "logstash-2018.02.19",  
"\_type" : "doc",  
"\_id" : "daUerWEBZrue2cT4uG7q",  
"\_score" : 1.0,  
"\_source" : {  
"app" : "core",  
"threadname" : "[DiscoveryClient-CacheRefreshExecutor-0]",  
"exception" : "ConnectTimeout",  
"@version" : "1",  
"host" : "sana-OptiPlex-3020",  
"@timestamp" : "2018-02-19T08:12:04.836Z",  
"LEVEL" : "WARN",  
"type" : "syslog",  
"path" : "/home/sana/Bureau/core/dataAndTranslation-2018-01-17.0.log",  
"message" : "RetryableEurekaHttpClient: Request execution failed with message: org.apache.http.conn.ConnectTimeoutException: Connect to jhipster-registry:8761 timed out",  
"logtime" : "2018-01-17 17:54:37,400"  
}  
},

and i want throught A spring boot application to do a vertical split: send all the values that exception could have and save them in mongodb collection.  
so please how to do this aggregation using spring boot and elasticsearch
