anchor.diff:  be able to cope with `max_failures` node failures at once at most, then the
   right number of replicas for you is
   `max(max_failures, ceil(num_nodes / num_primaries) - 1)`.

positive.code:  - the Profile API as a debugging tool adds significant overhead to search execution and can also have a very verbose output
   - given the added overhead, the resulting took times are not reliable indicators of actual took time, but can be used comparatively between clauses for relative timing differences
   - the Profile API is best for exploring possible reasons behind the most costly clauses of a query but isn't intended for accurately measuring absolute timings of each clause 
  
  
negative.code: and reduce latency for search-heavy applications.
