In OpenCGA, stats refers to the arrangement of search results into categories based on indexed field. Results are presented as a list of buckets, where each bucket is composed of 1) the field value and 2) a numerical count of how many matching documents were found for that field. In literature, this stats concept is known as facet or faceting as well. In fact, OpenCGA stats are based on Solr faceted search.
In addition, statsaddtion, stats allows users to query:
- Ranges that allow users to count how many documents are in an interval of a numerical field.
- Aggregation functions such as average, maximum, minimum, percentiles,...
- Nested faceted search.
