Perhaps you should try some spelling variations:
transport varies » transport barriers, transport tariffs, transport charges
set transport » sea transport, heat transport, salt transport
varies across » varied across, values across, variables across
a transformed » _ transformed, _ transformer, a transforming
transformed 1 » transformed _, transformer 1, transformed a
halal a » galal a, halal _, hall a
1 cacao » du cacao
agua a » agua la, agua e, agua 2
a set » _ set

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: (( agua a set transport varies across ) OR ( agua halal a transformed 1 cacao ))~.
• Adding a wildcard symbol may retrieve word variants: (( agua a set transport varies across ) or ( agua halal a transformed 1 cacao ))*.
