john ngosong » john song
man changed » main changes, has changed, a changed
long tail » long haul
long tip » long trip, long time, long did
role can » role a
can john » can join, cogan john, chen john
sein » seine, ein, seen

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((long tip) or (long tail)) ((than changed) OR (man changed)) role can john ngosong sein ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((long tip) OR (long tail)) ((than changed) OR (man changed)) role can john ngosong sein ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((long tip) or (long tail)) ((than changed) OR (man changed)) role can john ngosong sein ;".
• Adding a wildcard symbol may retrieve word variants: ((long tip) or (long tail)) ((than changed) OR (man changed)) role can john ngosong sein ;*.
