I'm a bit confused to see this so highly upvoted. I'm not sure you understand what MapReduce is for. MapReduce is not a technology designed for executing a search query in under 100ms, it's for massive data processing jobs. MapReduce is what you would use to do to prepare an index, not to query it.

As you yourself noted, this is blocked to prevent people from searching for SSN/credit card/etc. dumps.
