Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
par bonds » par bond, war bonds, war bond
bonds can » bonds a, bonds law, words can
sharing a » sharing _
kong weak » long weak
can cost » can costa, can lost, can post
kong sek » kong sar, kong k, kong lee
wan par » gan part, man part

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: wan par bonds can cost sharing a ((kong sek) OR (kong weak)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan par bonds can cost sharing a ((kong sek) or (kong weak)) ;*.
