Search doesn't work under certain circumstances

[jkleinsc]

Expected behavior:
Search should return matching results
Actual behavior:
Under certain circumstances, search either errors out or doesn't return results.
Steps to reproduce:
There are two different issues:

1. When using ElasticSearch, a text search doesn't always return back the records it should. For example, if there is a patient with the first name of "John", searching for John doesn't always return back that patient.
2. When ElasticSearch isn't enabled (config.searchURL is not configured - default value is not configured), there is a "slow" search that basically uses a temp couch view to search the database. This search works for users who are system admins, but it fails for users who are not system admins.
