[jira] Created: (LUCENE-1432) BitSet cannot be cast to DocIdSet
BitSet cannot be cast to DocIdSet
---------------------------------
Key: LUCENE-1432
URL: https://issues.apache.org/jira/browse/LUCENE-1432
Project: Lucene - Java
Issue Type: Bug
Components: Search
Affects Versions: 2.4
Reporter: Wouter Heijke
We recently upgraded from Lucene 2.3.1 to 2.4.0.
We left the code as-is apart from the needed changes to the package name for snowball, everything seems to run as before... Until yesterday when we started noticing the following stacktrace:
java.lang.ClassCastException: java.util.BitSet cannot be cast to org.apache.lucene.search.DocIdSet
org.apache.lucene.search.CachingWrapperFilter.getDocIdSet(CachingWrapperFilter.java:76)
org.apache.lucene.misc.ChainedFilter.getDocIdSet(ChainedFilter.java:200)
org.apache.lucene.misc.ChainedFilter.getDocIdSet(ChainedFilter.java:145)
org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:140)
org.apache.lucene.search.IndexSearcher.search(IndexSearcher.java:112)
org.apache.lucene.search.Searcher.search(Searcher.java:136)
Our index is 15gb in size and was made with Lucene 2.4.0.
The index holds around 36 million (Lucene) documents and 268 million terms.

Yep, likely conflict ahead here at the next svn up. Never mind, I'll leave the docIdSetToCache method in for LUCENE-1296 .

This patch should fix the problem.
However, the implementation of the bits() method is so inefficient that it might actually motivate users to avoid it.
The patch also contains a docIdSetToCache() method with the DocIdSet and the IndexReader as arguments, as discussed at LUCENE-1296.

---------------------------------------
Yes, the application calls bits() somewhere. I had just changed bits() into getDocIdSet() before your comment so this was the right thing to do, at least to fix the problem for now. Thanks!

[jira] Commented: (LUCENE-1432) BitSet cannot be cast to DocIdSet

Mark Harwood commented on LUCENE-1432:
--------------------------------------
Does your application code call the deprecated Filter.bits(reader) on the CachingWrapperFilter anywhere?
This would cause CachingWrapperFilter to cache an old-style bitset but the standard Lucene search will subsequently call Filter.getDocIdSet(reader) which always expects a DocIdSet to have been cached.
Ideally CachingWrapperFilter should be capable of recognising and adapting to this mix of filtering styles - at least while Lucene still maintains support for both Filter.getDocIdSet() AND Filter.bits().
In the interim, try replace any application code that calls bits() with getDocIdSet() if possible.

[jira] Updated: (LUCENE-1432) BitSet cannot be cast to DocIdSet
Posted by "Paul Elschot (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/LUCENE-1432?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Elschot updated LUCENE-1432:
---------------------------------
Attachment: LUCENE-1432.patch
This patch should fix the problem.
However, the implementation of the bits() method is so inefficient that it might actually motivate users to avoid it.
The patch also contains a docIdSetToCache() method with the Filter and the IndexReader as arguments, as discussed at LUCENE-1296.
