Robert Muir commented on LUCENE-4069:
-------------------------------------
I don't think the abstract class should be registered in the SPI.
Instead i think the concrete Bloom+Lucene40 that you have in tests should be
moved into src/java and registered there, just call it Bloom40 or something.
The abstract api is still available for someone that wants to do something more
specialized.
This is just like how pulsing (another wrapper) is implemented.
As far as disabling this for certain tests, import
o.a.l.util.LuceneTestCase.SuppressCodecs and put something like this at class
level:
{code}
@SuppressCodecs("Bloom40")
public class TestFoo...
@SuppressCodecs({"Bloom40", "Memory"})
public class TestBar...
{code}

> Key: LUCENE-4069
> URL: https://issues.apache.org/jira/browse/LUCENE-4069
> Project: Lucene - Java
> Issue Type: Improvement
> Components: core/index
> Affects Versions: 3.6, 4.0
> Reporter: Mark Harwood
> Priority: Minor
> Fix For: 4.0, 3.6.1
>
> Attachments: BloomFilterPostings40.patch,
> MHBloomFilterOn3.6Branch.patch, PrimaryKey40PerformanceTestSrc.zip
>
>
> An addition to each segment which stores a Bloom filter for selected fields
> in order to give fast-fail to term searches, helping avoid wasted disk access.
> Best suited for low-frequency fields e.g. primary keys on big indexes with
> many segments but also speeds up general searching in my tests.
> Overview slideshow here:
> http://www.slideshare.net/MarkHarwood/lucene-bloomfilteredsegments
> Benchmarks based on Wikipedia content here: http://goo.gl/X7QqU
> Patch based on 3.6 codebase attached.
> There are no 3.6 API changes currently - to play just add a field with "_blm"
> on the end of the name to invoke special indexing/querying capability.
> Clearly a new Field or schema declaration(!) would need adding to APIs to
> configure the service properly.
> Also, a patch for Lucene4.0 codebase introducing a new PostingsFormat
