java.lang.Objectorg.apache.jackrabbit.core.query.lucene.IndexFormatVersion
public class IndexFormatVersion
This class indicates the lucene index format that is used. Version 1 formats
do not have the PROPERTIES_SET
lucene fieldname and queries
assuming this format also run on newer versions. When the index is recreated
from scratch, the Version 2 format will automatically be used. This format is
faster certain queries, so if the index does not contain
PROPERTIES_SET
fieldname and re-indexing is an option, this is
advisable. Existing indexes are not automatically upgraded to a newer
version!
