Talvez debería tentar con algunhas variantes ortográficas:
information documents » information documentation, information agents, information requirements
a imprecision » _ imprecision, a precision, data imprecision
data creating » data cleaning
data getting » data fitting, data testing, data detecting
documents a » documents _

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: information documents a imprecision ((data creating) OR (((data getting) OR (a testing))))~.
• Adding a wildcard symbol may retrieve word variants: information documents a imprecision ((data creating) or (((data getting) or (a testing))))*.
