Michael McCandless commented on LUCENE-2327:
--------------------------------------------
Yikes -- you had 10 corrupted segments (of 23) and there's at least 4 different
flavors of corruption across those segments! Curious... What storage device
did you store the index on? ;)
Note the that "fix" just drops those segments from the index, so any docs that
were in them are lost.

> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 3.0.1
> Environment: Fedora 12
> Reporter: Shane
> Priority: Minor
> Attachments: CheckIndex.txt

> When retrieving the scoreDocs from a multisearcher, the following exception
> is thrown:
> java.lang.IndexOutOfBoundsException: Index: 52, Size: 4

> The error is caused when the fieldNumber passed to FieldInfos.fieldInfo() is
> greater than the size of array list containing the FieldInfo values. I am
> not sure what the field number represents or why it would be larger than the
> array list's size. The quick fix would be to validate the bounds but there
> may be a bigger underlying problem. The issue does appear to be directly
> related to LUCENE-939. I've only been able to duplicate this in my
> production environment and so can't give a good test case.
