Filtering using 'or'

Hi,

I'm trying to filter my issue list to show submitted issues of either type 'user feature' or type 'technical feature'. I'm trying to do it like this

1. Submitted (#{User Feature} or #{Technical feature})

but that's not working. Anyone know how I can do it? I know I can write

1. Submitted #{User Feature} or #Submitted #{Technical feature}

but then I am duplicating all the "and" terms.

Regards,
Philip
