Perhaps you should try some spelling variations:
ideas transform » ideas transport, ideals transforming, leaders transform
transform pairs » transform haar, transform cities, transform crisis
2 ideas » _ ideas
cost 15 » cost 12, cost 11.5, cost 1.2
luis 2 » luis c, luis a, luis e
f heat » _ heat, a heat, 1 heat
cost 5 » cost _, cost 4, cost 7

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 2 ideas transform pairs marc ) OR ( luis f heat transfer ((cost 5) OR (cost 15)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis 2 ideas transform pairs marc ) or ( luis f heat transfer ((cost 5) OR (cost 15)) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis 2 ideas transform pairs marc ) or ( luis f heat transfer ((cost 5) OR (cost 15)) ))*.
