Unable to get values after searching for a Special Character

[paramzvik (Vikram Sai Simha Vissamsetti)]

Hi Fellow Developers,

I am using the following query to fetch data for the titles having + as a field in them but not returning any value.
Can someone help me out in rectifying the issue.
"query_string":{"query":"\+","fields":["__title"],"default_operator":"and","boost":0.1}
