Long load time for search Documents impedes Carousel loading

[jvwong]

The home component makes two closely staggered web service calls to retrieve documents: First to retrieve all public docs for the search (longer running) then the carousel to retrieve a recent slice. It seems that when the cache is empty, the latter is bottle-necked by the former. This has the effect of making the carousel load slow at the cost of the search.

You have to explicitly use the getAll command to take advantage of secondary indexes.

If we don't use the index, it will be slow

This issue is mitigated by updates in #1054. Will have to look at standalone search when DB size increases.
