Perhaps you should try some spelling variations:
cow transformed » law transformed, _ transformed, a transformed
transport ties » transport times, transport trips, transport time
guias dead » guias de
ties data » studies data
does air » does pair, does aid, does asia
dead cow » mad cow, dead job

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: (( guias ((de air) OR (does air)) transport ties data ) OR ( guias dead cow transformed _ cacao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( guias ((de air) OR (does air)) transport ties data ) or ( guias dead cow transformed _ cacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( guias ((de air) OR (does air)) transport ties data ) or ( guias dead cow transformed _ cacao ))*.
