SOS-2487 / SOS-2476 / SOS-2492

Hey Jon,

I brought back in the first two regressions and then resolved the issue of "autocomplete.recipient.type" not working properly using the UserIndexerPostProcessor, like you suggested. I opted for using the Indexer.DEFAULT_INTERVAL just in case a user has many connections. Also, I wasn't sure about the naming of the index keyword.

Let me know if you have any questions. Thanks.
