Perhaps you should try some spelling variations:
information documents » information documentation, information agents, information requirements
data imprecision » based imprecision, table imprecision, data compression
documents data » documents a
data creating » data cleaning
data penting » data getting, data presenting, data planning
data testing » data fitting, a testing, data writing

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