Hi all!  
I have a record in index, that contains some spec characters " ", "/", "-":

{  
"documentData" :  
{  
"refNo" : "8652 / 58996-3",  
"status" : "Rejected",  
}  
}

How should I do query\_string search if I have only "8652589963" value?  
Thanks!

"query\_string": {  
"query": "(documentData.refNo: /86525[\/ -]8996[\/ -]3/)"  
} - it doesn't work.

I answer myself:  
"query\_string": {  
"query": "xmlData.refNo.keyword:/8[\.\-\\\/]\*6[\.\-\\\/]\*5[\.\-\\\/]\*2[\.\-\\\/]\*5[\.\-\\\/]\*8[\.\-\\\/]\*9[\.\-\\\/]\*9[\.\-\\\/]\*6[\.\-\\\/]_3[\.\-\\\/]_/"  
}
