Investigate how best to uncover complex object children in browse/search

[elizoller]

The complex object children can clutter up the browse/search results.
some ideas would be to

• adjust the weight so parent objects would come up first
• not show complex objects at all but show parents only (this would require us to think about how one would search for metadata that is within a complex object only)

for now, we've decided the best course of action would be to limit searching so that it does not return children of objects which have the model "paged content" to remove "page" like objects from results.
