Overview

This is a faked response for a solr timeout. Why? In some cases, Solr will timeout, but there will be no response. Instead Ruby will raise a Timeout::Error, which the indexer does not handle, causing the indexer to crash in the index round. Instead we will rescue the timeout error and return this faked response.
