Perhaps you should try some spelling variations:
works looking » work looking, works working, world looking
works loading » works reading
can chung » man chung, fan chung, can change
lan chung » man chung, lin chung, fan chung
2008 acm » 2008 a, 2008 a2, 2008 a1

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: 2008 acm ((works looking) OR (works loading)) league ((can chung) OR (lan chung)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "2008 acm ((works looking) OR (works loading)) league ((can chung) or (lan chung))".
• Adding a wildcard symbol may retrieve word variants: 2008 acm ((works looking) OR (works loading)) league ((can chung) or (lan chung))*.
