Query profiling

A new feature available in Elasticsearch 5.x is the profile API. This allows the user to track the time spent by Elasticsearch in executing a search or an aggregation.

Getting ready

You will need an up-and-running Elasticsearch installation as used in the Downloading and installing Elasticsearch recipe in Chapter 2, Downloading and Setup.

To execute curl via a command line, you need to install curl for your operating system.

           pretty' -d '{
               "profile": true,
               "query": {
                   "term": {
                       "uuid": "11111"
                   }
