[jira] [Created] (LUCENE-4965) Add dynamic numeric range faceting
Michael McCandless created LUCENE-4965:
------------------------------------------
Summary: Add dynamic numeric range faceting
Key: LUCENE-4965
URL: https://issues.apache.org/jira/browse/LUCENE-4965
Project: Lucene - Core
Issue Type: Improvement
Components: modules/facet
Reporter: Michael McCandless
Assignee: Michael McCandless
Fix For: 5.0, 4.4
The facet module today requires the app to compute the hierarchy
at index time, eg a timestamp field might use a year/month/day
hierarchy.
While this gives great performance, since it minimizes the search-time
computation, sometimes it's unfortunately useful/necessary to do things entirely at
search time, like Solr does.
E.g. I'm playing with a prototype Lucene search for Jira issues
and I'd like to add a drill down+sideways for "Updated in past day,
2 days, week, month" etc. But because time is constantly advancing,
doing this at index time is a not easy ...
