Talvez debería tentar con algunhas variantes ortográficas:
information documents » information documentation, information agents, information requirements
between pearson's » between persons, between personal, between person
data operators » data operations, beta operators, meta operators
java operators » gamma operators, halal operators, owa operators

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 ((data operators) OR (java operators)) between pearson's~.
• Adding a wildcard symbol may retrieve word variants: information documents ((data operators) or (java operators)) between pearson's*.
