Subject [jira] Created: (LUCENE-1720) TimeLimitedIndexReader and associated utility class
Date Sun, 28 Jun 2009 22:14:47 GMT
TimeLimitedIndexReader and associated utility class
---------------------------------------------------

                 Key: LUCENE-1720
                 URL: https://issues.apache.org/jira/browse/LUCENE-1720
             Project: Lucene - Java
          Issue Type: New Feature
          Components: Index
            Reporter: Mark Harwood
            Assignee: Mark Harwood
            Priority: Minor


An alternative to TimeLimitedCollector that has the following advantages:

1) Any reader activity can be time-limited rather than just single searches e.g. the document
retrieve phase.
2) Times out faster (i.e. runaway queries such as fuzzies detected quickly before last "collect"
stage of query processing)

Uses new utility timeout class that is independent of IndexReader.

Initial contribution includes a performance test class but not had time as yet to work up
a formal Junit test.
TimeLimitedIndexReader is coded as JDK1.5 but can easily be undone.
