--------------------------------------
Summary: Facet sampling
Key: LUCENE-5476
URL: https://issues.apache.org/jira/browse/LUCENE-5476
Project: Lucene - Core
Issue Type: Improvement
Reporter: Rob Audenaerde
With LUCENE-5339 facet sampling disappeared.
When trying to display facet counts on large datasets (>10M documents) counting
facets is rather expensive, as all the hits are collected and processed.
Sampling greatly reduced this and thus provided a nice speedup. Could it be
brought back?
