How to add Special Characters while creating Complex filters in TCC ?

Content

Hi,

I was trying to filter out few requisitions on the basis of Candidate CSW Status. Since multiple statuses are availale, I tried using a complex filter to add them. But the CSW Status contained certain Special characters like "&" ,"%" etc in them and hence the complex filter that was created throwed an error "Code is not Valid". Could some one suggest me a way to overcome this ?

Thanks and Regards,
