Talvez debería tentar con algunhas variantes ortográficas:
conservation documentation » observation documentation, information documentation, conservation foundation
control documentation » control instrumentation, control implementation, care documentation
3 curtan » _ curtain, _ cartan, _ curtin
can war » can wear, can work, can bear

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

• Performing a fuzzy search may retrieve terms with similar spellings: can war ((control documentation) or (conservation documentation)) 3 curtan-metragem~.
• If you are trying to use Boolean operators, they must be ALL CAPS: can war ((control documentation) OR (conservation documentation)) 3 curtan-metragem.
• Adding a wildcard symbol may retrieve word variants: can war ((control documentation) or (conservation documentation)) 3 curtan-metragem*.
