Talvez debería tentar con algunhas variantes ortográficas:
information documents » information documentation, information agents, information requirements
documents separating » document separation, documents generating, documents evaluating
separating execution » preparation execution, separating reflection, separating precision
data peng » data penting
data pet » data peter, data petri, data part

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 separating execution ((data peng) or (data pet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information documents separating execution ((data peng) OR (data pet)).
• Adding a wildcard symbol may retrieve word variants: information documents separating execution ((data peng) or (data pet))*.
