----------------------------------------------
Key: LUCENE-1116
URL: https://issues.apache.org/jira/browse/LUCENE-1116
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/benchmark
Affects Versions: 2.2
Reporter: Doron Cohen
Assignee: Doron Cohen
Priority: Minor
Fix For: 2.3
Few fixes and improvements for the search quality benchmark package:
- flush report and logger at the end (otherwise long submission reports might
miss last lines).
- add run-tag-name to submission report (API change).
- add control over max-#queries to run (useful at debugging a quality
evaluation setup).
- move control over max-docs-to-retrieve from benchmark constructor to a setter
method (API change).
- add computation of Mean Reciprocal Rank (MRR) in QualityStats.
- QualityStats fixed to not fail if there are no results to average.
- Add a TREC queries reader adequate for the 1MQ track (track started 2007).
All tests pass, will commit this in 1-2 days if there is no objection.
