Summary: Add facets impl to count unique numeric values
Key: LUCENE-7927
URL: https://issues.apache.org/jira/browse/LUCENE-7927
Project: Lucene - Core
Issue Type: Improvement
Components: modules/facet
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 7.1
The facets module has multiple facet methods for counting flat and hierarchical
fields, and also a method for counting numeric ranges. I'd like to also add a
method that counts unique numeric (long) values, designed to be used for fields
that have only a few, typically low valued, numbers across the index e.g. a
"review" rating from 1 to 5.
