Perhaps you should try some spelling variations:
2c radio » 2 radio, 22 radio, 28 radio
c radio » 2 radio, 7 radio, 8 radio
2c tv » pc tv
2c tc » 23 tc, 2a tc, 2c c
2b tc » 2b 2c, 23 tc, 2a tc
c tv » pc tv, _ tv, c v

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: %22print%((2c radio) OR (c radio))%((((((((2c tv) OR (c tv))) OR (((2c tc) OR (2b tc))))) OR (27 tv))) OR (2c pv)) %_ cinema%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22print%((2c radio) or (c radio))%((((((((2c tv) OR (c tv))) or (((2c tc) or (2b tc))))) or (27 tv))) or (2c pv)) %_ cinema%22".
• Adding a wildcard symbol may retrieve word variants: %22print%((2c radio) or (c radio))%((((((((2c tv) OR (c tv))) or (((2c tc) or (2b tc))))) or (27 tv))) or (2c pv)) %_ cinema%22*.
