Perhaps you should try some spelling variations:
1.4 training » 12.4 training, 2.4 training, 1.3 training
1.4 raising » 13.3 raising, 1 raising, 11 raising
more change » make change, code change, forest change
change big » changes big, change bio, change bad
wang yang » wang yan, wang liang, wang yanling
li qiang » li xiang, li keqiang, wei qiang

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: wang ((wang yang) OR (li qiang)) cio ((1.4 raising) OR (1.4 training)) more change big ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang yang) or (li qiang)) cio ((1.4 raising) OR (1.4 training)) more change big ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang yang) or (li qiang)) cio ((1.4 raising) OR (1.4 training)) more change big ;*.
