Talvez debería tentar con algunhas variantes ortográficas:
information documents » information documentation, information agents, information requirements
imprecision data » precision data, imprecise data, imperfection data
information age » information storage
imprecision a » imprecision _, precision a, precision _

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((information documents) or (information age)) a ((imprecision data) OR (imprecision a)) penting~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((information documents) OR (information age)) a ((imprecision data) OR (imprecision a)) penting.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((information documents) or (information age)) a ((imprecision data) OR (imprecision a)) penting".
• Adding a wildcard symbol may retrieve word variants: ((information documents) or (information age)) a ((imprecision data) OR (imprecision a)) penting*.
