your cost » your most, your best, your boss
cost data » test data
can young » kang young, can you, a young
cyn young » lynn young, yun young, c young
dann bin » dong bin
pay your » day your, way your, way you
wai yan » wang yan, wei yang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((wai yan) or (((yang yang) or (dann bin)))) pay your cost data ((can young) OR (cyn young)) yun ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wai yan) OR (((yang yang) OR (dann bin)))) pay your cost data ((can young) OR (cyn young)) yun ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wai yan) or (((yang yang) or (dann bin)))) pay your cost data ((can young) OR (cyn young)) yun ;".
• Adding a wildcard symbol may retrieve word variants: ((wai yan) or (((yang yang) or (dann bin)))) pay your cost data ((can young) OR (cyn young)) yun ;*.
