Deprecated Interfaces
org.apache.lucene.search.Searchable In 4.0 this interface is removed/absorbed into IndexSearcher
org.apache.lucene.analysis.tokenattributes.TermAttribute Use `CharTermAttribute` instead.

Deprecated Classes
org.apache.lucene.analysis.CharArraySet.CharArraySetIterator Use the standard iterator, which returns `char[]` instances.
org.apache.lucene.document.DateField If you build a new index, use `DateTools` or `NumericField` instead. This class is included for use with existing indices and will be removed in a future release (possibly Lucene 4.0).
org.apache.lucene.search.FilterManager used by remote package which is deprecated as well. You should use `CachingWrapperFilter` if you wish to cache `Filter`s.
org.apache.lucene.index.IndexWriter.MaxFieldLength use `LimitTokenCountAnalyzer` instead.
org.apache.lucene.analysis.ISOLatin1AccentFilter If you build a new index, use `ASCIIFoldingFilter` which covers a superset of Latin 1. This class is included for use with existing indexes and will be removed in a future release (possibly Lucene 4.0).
org.apache.lucene.search.MultiSearcher If you are using MultiSearcher over IndexSearchers, please use MultiReader instead; this class does not properly handle certain kinds of queries (see LUCENE-2756).
org.apache.lucene.document.NumberTools For new indexes use `NumericUtils` instead, which provides a sortable binary representation (prefix encoded) of numeric values. To index and efficiently query numeric values use `NumericField` and `NumericRangeQuery`. This class is included for use with existing indices and will be removed in a future release (possibly Lucene 4.0).
org.apache.lucene.search.ParallelMultiSearcher Please pass an ExecutorService to `IndexSearcher`, instead.
org.apache.lucene.util.Parameter Use Java 5 enum, will be removed in a later Lucene 3.x release.
