pass 2 or more args to a view

Hi

I have a view with node title filter exposed

example.com/myview

I am able to create a view with one argument
'CC 1' is a node title

example.com/myview?op0=contains&filter0=CC+1

How do I pass two or more node titles as arguments to a view
I have tried

CC 1,CC2

example.com/myview?op0=contains&filter0=CC+1%2CCC+2

CC 1+CC2

example.com/myview?op0=contains&filter0=CC+1%2BCC+2

CC 1&CC2

example.com/myview?op0=contains&filter0=CC+1%26CC+2

None worked

Regards
G
