Perhaps you should try some spelling variations:
a transformer » _ transformer, a transformed, 3 transformer
transformer 1 » transformer _, transformed _
costs across » scores across, risks across
agua lab » agua la
2 gas » _ gas
3 gas » _ gas
lab a » lab _, law a, bab a
1 cao » 1 can, 1 ao, _ cao

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 ((2 gas) OR (3 gas)) transport costs across ) OR ( agua lab a transformer 1 cao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agua ((2 gas) OR (3 gas)) transport costs across ) or ( agua lab a transformer 1 cao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agua ((2 gas) OR (3 gas)) transport costs across ) or ( agua lab a transformer 1 cao ))*.
