Perhaps you should try some spelling variations:
bring back » going back, bringing back, turning back
bond sara » bond sale
bond data » beyond data, board data, round data
lang yan » wang yan, wang yang, zhang yan
yan yang » yang yang, yao yang, dan yang
ten most » ten mostly, than most, when most
can best » can boost

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: lang yan yang ((ten most) OR (can best)) bring back ((bond sara) OR (bond data)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yan yang ((ten most) or (can best)) bring back ((bond sara) OR (bond data)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yan yang ((ten most) or (can best)) bring back ((bond sara) OR (bond data)) ;*.
