Hello,

I'm working on an elasticsearch 2.4 and i can't modify the mapping.  
The field that interests me in the mapping:

"message": {  
"analyzer": "standard",  
"doc\_values": false,  
"index": true,  
"standards": false,  
"type": "text"  
}

This field contains the logs of type: "1:X 18 Jun 17:25:54.312 # ERROR text error"

I wish research on the '#' character to display only the lines with this character.  
Is it possible to search special characters without modifying the standard tokenizer / analyzer?

Thank for your help.  
Christophe.
