No quotes.

Ordinarily to match the above with exactly one space, you would use

television comedy

as your re, but in the case of Topics, the re is compiled in IGNORECASE
and VERBOSE mode. IGNORECASE makes it case insensitive which is
normally good. VERBOSE enables certain 'readability' features, one of
which is to ignore certain whitespace in patterns, so the above won't
work. To match with exactly one space, you need

television\ comedy


television[ ]comedy

More likely you want any number (>1) of spaces or tabs in which case
you use

television[ \t]+comedy

or for any amount of whitespace
