How to search special Characters

[#1]

I have a FIeld which has names like

Product(A)

Market(A)

Product(B)

Market(B)

I want to search all the values which has (A) in it.

The field is used as dimension and i have activated Dropdown select so i can search values in the dimension column. But i am not able to search (A). How do we search special characters ??

Sumit, You can use the expression like =if(WildMatch([product], '*(A)*') = 1,[product], null()) to filter.  Find the attached qvw file if it helps.
