Perhaps you should try some spelling variations:
best when » bent when, best what, text when
debt when » debt we, debt what
kong star » kong sar
kong yam » kong sar
yam land » farm land, das land, dem land
land how » hand how, lane how, sand how
kong sek » kong weak, kong sar, kong k

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: kong yam land how ((best when) OR (debt when)) eng ((kong sek) OR (kong star)) ;~.
• Adding a wildcard symbol may retrieve word variants: kong yam land how ((best when) or (debt when)) eng ((kong sek) or (kong star)) ;*.
