Joel Bernstein updated SOLR-13047: ---------------------------------- Description: The current facet expression is a generic tool for creating multi-dimension aggregations. The *facet2D* Streaming Expression has semantics specific to 2 dimensional facets which are designed to be pivoted into a matrix and operated on by Math Expressions. facet2D will use the json facet API under the covers. Proposed syntax: {code:java} facet2D(medrecords, q=*:*, x=diseases, y=symptom, dimensions="300, 10", count(*)){code} The example above will return tuples containing the top 300 diseases and the top ten symptoms for each disease. was: The current facet expression is a generic tool for creating multi-dimension aggregations.
