问题
Is there any way in which I can search for phrases with special characters in the content of the attached file? for eg: I want to search for asn@xyz.com in the contents of all the indexed files.
I actually tried it on my code and it seems to be like '@' is not considered and instead it is searching for asn, xyz and com separately and generating results. How can I solve this?
TIA
