Perhaps you should try some spelling variations:
synthesize » synthesized, synthesis, synthese
synthesizeds » synthesizedds, synthesisds, syntheseds, synthesized, synthesizes, synthesizers
synthesisds » synthesises, synthesisers, synthesis
synthesiss » synthesises, synthesis, synthesise

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: ( synthesize OR ( (synthesizeds OR synthesisds) OR synthesiss )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( synthesize or ( (synthesizeds OR synthesisds) or synthesiss ))".
• Adding a wildcard symbol may retrieve word variants: ( synthesize or ( (synthesizeds OR synthesisds) or synthesiss ))*.
