How to search such values :- 1/2"-12

Hello Folks,

I have a such data

doc1 -> { "Data" : "1/2"-12"}
doc2 -> { "Data" : "3/4"-22"}
doc3 -> { "Data" : "1/8"-42"}
doc4 -> { "Data" : "4/13"-2"}
*doc5 -> { "Data" : "13/24"-27"} *

where data is mapped as a string. {"Data":{"type":"String"}}

I am using following query for search :-

{"query_string": {"query": "Data:1\/2\"-12"}}

but I am getting irrelevant response.

Can you please suggest me some ways to track it..

Thanks in advance...!!

Thanks
Mohit
