Empty autocomplete suggestions

[abelemlih]

While doing some performance troubleshooting, I noticed that the application is sending requests to the server for autocomplete suggestions ( e.g. https://search.libraries.emory.edu/catalog/suggest?q=data%20science when a user searches for "data science"). All suggestion requests get an empty response back from the server.

@tclayton33 I am aware this is a Blacklight feature that we currently have enabled in the application but that never actually worked. If there is an interest in having autocomplete suggestions when users search, we should figure out the cause of the empty responses from the /suggest endpoint and fix it. Otherwise, we should disable the feature entirely in the application configuration.
