Hi,

We are using FTS to implement search and there is a scenario where we have a
word say "IVR@#1", when I search for "1" there should not be any result as
per user perspective.
It seems special characters are replaced by spaces/blanks. Is there any way
to include Special characters in search? Kindly let us know through this
channel as earliest possible.

Regards
