-#### Stats
-If stats is enabled the facets returned will in addition to the term and a count contain `max`, `min`, `mean` and `total` fields for the score in each facet. This is very useful if you want to be able to sort facets on relevance rather than count.
+Use the `stats` option to get to max, min, mean, and total scores for each facet
 
 ```ruby
-Product.search "*", facets: {store_id: { stats: true }}
+Product.search "*", facets: {store_id: {stats: true}}
