Hi there,

I was trying to create a filter to match field "source" and value "/var/log/nginx/\*-access.log", the log file name contains the domain name, e.g, /var/log/nginx/mydomain.com-access.log, couldn't get it work, help please.

{  
"query": {  
"match": {  
"source": {  
"query": "/var/log/nginx/\*-access.log",  
"type": "phrase"  
}  
}  
}  
}
