• If you are trying to use Boolean operators, they must be ALL CAPS: ((2008 ilo) OR (2008 iso)) world does ((imagery virtual) OR (images virtual)) thermo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((2008 ilo) OR (2008 iso)) world does ((imagery virtual) or (images virtual)) thermo".
• Adding a wildcard symbol may retrieve word variants: ((2008 ilo) OR (2008 iso)) world does ((imagery virtual) or (images virtual)) thermo*.
