Perhaps you should try some spelling variations:
things chapter » things happen, findings chapter, thinking chapter
thing change » things change, using change, teaching change
time last » time list, time past, time lost
tan yong » tan hong, tan kong, tan yang
robert j » robert _, robert e
yong vi » yong kim, yong cai
vi time » ii time, i time, ndvi time

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: tan yong vi time last ((thing change) OR (things chapter)) robert j ;~.
• Adding a wildcard symbol may retrieve word variants: tan yong vi time last ((thing change) or (things chapter)) robert j ;*.
