Perhaps you should try some spelling variations:
experimentals » experimentales, experimental, experimentale, experimentalls, experimentarls, experimentsls
experimenta » experimental, experimentar, experiments
experimentos » experimental, experimentals
experimento » experimental
experimentor » experimentalr, experimentar, experimenter, experimentador

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "thought (experimentals OR (experimenta OR ((experimentos OR experimento) OR experimentor)))~".
• Adding a wildcard symbol may retrieve word variants: thought (experimentals OR (experimenta OR ((experimentos OR experimento) OR experimentor)))*.
