Perhaps you should try some spelling variations:
exchange reserve » exchange reserves
daily exchange » parity exchange, data exchange, city exchange
reserve using » research using, nerve using
act daily » a daily
tan ying » fan ying, ran ying, tan yang
iii time » ii time
yi time » ii time
i time » ii time, 3 time, 4 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 ying ((((yi time) OR (iii time))) OR (i time)) act daily exchange reserve using ;~.
• Adding a wildcard symbol may retrieve word variants: tan ying ((((yi time) or (iii time))) or (i time)) act daily exchange reserve using ;*.
