Perhaps you should try some spelling variations:
information aggregation » information integration, information propagation, information organization
aggregation function » aggregation functions, aggregate functions, aggregation factor
function decisions » functions decision, function designs, function definitions
data shared » data share, data shape, data spare
data while » data file
data why » data what, data web

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

• Performing a fuzzy search may retrieve terms with similar spellings: information aggregation function decisions ((data shared) or (((data why) or (data while))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: information aggregation function decisions ((data shared) OR (((data why) OR (data while)))).
• Adding a wildcard symbol may retrieve word variants: information aggregation function decisions ((data shared) or (((data why) or (data while))))*.
