Perhaps you should try some spelling variations:
transfer amounts » transfer payments
transfer africa » transfer price
amounts case » points case
africa mark » africa market, africa macro, africa march
de data » wide data, de datos, age data
luis a » luis f, luis c
e data » e datas, age data, cge data

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: (( luis a _ transfer africa mark ) OR ( luis ((de data) OR (e data)) transfer amounts case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a _ transfer africa mark ) or ( luis ((de data) OR (e data)) transfer amounts case ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a _ transfer africa mark ) or ( luis ((de data) OR (e data)) transfer amounts case ))*.
