anchor.diff:  `global_aggregation`::
   
       A collector that executes an aggregation against the global query scope, rather than the specified query.
  -    Because the global scope is necessarily different from the executed query, it must execute it's own
  +    Because the global scope is necessarily different from the executed query, it must execute its own
       match_all query (which you will see added to the Query section) to collect your entire dataset
   
   
  
positive.code: 
  Because a search request may be executed against one or more shards in an index, and a search may cover
  one or more indices, the top level element in the profile response is an array of `shard` objects.
  Each shard object lists it's `id` which uniquely identifies the shard.  The ID's format is
  `[nodeID][indexName][shardID]`.
  
  The profile itself may consist of one or more "searches", where a search is a query executed against the underlying
  Lucene index.  Most Search Requests submitted by the user will only execute a single `search` against the Lucene index.
  But occasionally multiple searches will be executed, such as including a global aggregation (which needs to execute
  a secondary "match_all" query for the global context).
  
  Inside each `search` object there will be two arrays of profiled information:
  a `query` array and a `collector` array.  Alongside the `search` object is an `aggregations` object that contains the profile information for the aggregations. In the future, more sections may be added, such as `suggest`, `highlight`, etc
  
  There will also be a `rewrite` metric showing the total time spent rewriting the query (in nanoseconds).
  
  
negative.code: 
  `matches`::
  
      Some queries, such as phrase queries, match documents using a "two-phase" process.  First, the document is
      "approximately" matched, and if it matches approximately, it is checked a second time with a more rigorous
      (and expensive) process.  The second phase verification is what the `matches` statistic measures.
