caching.HighFreqTerms class extracts the top n most frequent terms
(by document frequency ) from an existing Lucene index and reports their
document frequency.Filter.PKIndexSplitter.PKIndexSplitter(Version, Directory, Directory, Directory, Filter) instead.
This constructor will be removed in Lucene 4.0.PKIndexSplitter.PKIndexSplitter(Version, Directory, Directory, Directory, Term)
instead. This constructor will be removed in Lucene 4.0.Filter.MultiPassIndexSplitter.split(Version, IndexReader, Directory[], boolean) instead.
This method will be removed in Lucene 4.0.Directory implementation for Microsoft Windows.NativeFSLockFactory.
