Deprecated Interfaces
org.apache.lucene.benchmark.Benchmarker Use the Task based benchmarker
org.apache.lucene.benchmark.BenchmarkOptions Use the task based approach instead
org.apache.lucene.index.IndexCommitPoint Please subclass IndexCommit class instead

Deprecated Classes
org.apache.lucene.benchmark.AbstractBenchmarker Use the Task based benchmarker
org.apache.lucene.document.DateField If you build a new index, use `DateTools` instead. This class is included for use with existing indices and will be removed in a future release.
org.apache.lucene.search.Hit Hits will be removed in Lucene 3.0. Use `TopDocCollector` and `TopDocs` instead.
org.apache.lucene.search.HitIterator Hits will be removed in Lucene 3.0. Use `TopDocCollector` and `TopDocs` instead.
org.apache.lucene.search.Hits Hits will be removed in Lucene 3.0. Instead e. g. `TopDocCollector` and `TopDocs` can be used:
       TopDocCollector collector = new TopDocCollector(hitsPerPage);
       searcher.search(query, collector);
       ScoreDoc[] hits = collector.topDocs().scoreDocs;
       for (int i = 0; i < hits.length; i++) {
         int docId = hits[i].doc;
         Document d = searcher.doc(docId);
         // do something with current hit
         ...
org.apache.lucene.index.IndexModifier Please use `IndexWriter` instead.
org.apache.lucene.search.QueryFilter use a CachingWrapperFilter with QueryWrapperFilter
org.apache.lucene.benchmark.standard.ReutersQueries Use Task based benchmarker
org.apache.lucene.benchmark.standard.StandardBenchmarker use the byTask code instead. See http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/benchmark/byTask/package-summary.html .
org.apache.lucene.benchmark.standard.StandardOptions Use the Task based stuff instead
org.apache.lucene.analysis.nl.WordlistLoader use `WordlistLoader` instead

Deprecated Fields
org.apache.lucene.analysis.standard.StandardTokenizer.ACRONYM_DEP this solves a bug where HOSTs that end with '.' are identified as ACRONYMs. It is deprecated and will be removed in the next release.
org.apache.lucene.search.highlight.Highlighter.DEFAULT_MAX_DOC_BYTES_TO_ANALYZE See `Highlighter.DEFAULT_MAX_CHARS_TO_ANALYZE`
org.apache.lucene.index.IndexWriter.DEFAULT_MAX_MERGE_DOCS
org.apache.lucene.index.IndexWriter.DEFAULT_MERGE_FACTOR
org.apache.lucene.store.FSDirectory.LOCK_DIR As of 2.1, `LOCK_DIR` is unused because the write.lock is now stored by default in the index directory. If you really want to store locks elsewhere you can create your own `SimpleFSLockFactory` (or `NativeFSLockFactory`, etc.) passing in your preferred lock directory. Then, pass this `LockFactory` instance to one of the `getDirectory` methods that take a `lockFactory` (for example, `FSDirectory.getDirectory(String, LockFactory)`).
org.apache.lucene.document.Field.Index.NO_NORMS This has been renamed to `Field.Index.NOT_ANALYZED_NO_NORMS`

org.apache.lucene.index.IndexWriter.addIndexes(Directory[]) Use `IndexWriter.addIndexesNoOptimize(org.apache.lucene.store.Directory[])` instead, then separately call `IndexWriter.optimize()` afterwards if you need to.
org.apache.lucene.document.Field.binaryValue() This method must allocate a new byte[] if the `AbstractField.getBinaryOffset()` is non-zero or `AbstractField.getBinaryLength()` is not the full length of the byte[]. Please use `AbstractField.getBinaryValue()` instead, which simply returns the byte[].
org.apache.lucene.search.RangeFilter.bits(IndexReader) Use `RangeFilter.getDocIdSet(IndexReader)` instead.

org.apache.lucene.index.IndexWriter.flush() please call `IndexWriter.commit()`) instead
org.apache.lucene.search.highlight.Highlighter.getBestFragments(Analyzer, String, int) This method incorrectly hardcodes the choice of fieldname. Use the method of the same name that takes a fieldname.

org.apache.lucene.queryParser.precedence.CharStream.getLine()

org.apache.lucene.analysis.standard.StandardAnalyzer.isReplaceInvalidAcronym() This will be removed (hardwired to true) in 3.0
org.apache.lucene.analysis.TokenStream.next() The returned Token is a "full private copy" (not re-used across calls to next()) but will be slower than calling `TokenStream.next(Token)` instead..
org.apache.lucene.store.IndexInput.readChars(char[], int, int) -- please use readString or readBytes instead, and construct the string from those utf8 bytes
org.apache.lucene.store.FSDirectory.renameFile(String, String)
org.apache.lucene.store.Directory.renameFile(String, String)

org.apache.lucene.store.IndexInput.skipChars(int) this method operates on old "modified utf8" encoded strings
org.apache.lucene.analysis.Token.termText() This method now has a performance penalty because the text is stored internally in a char[]. If possible, use `Token.termBuffer()` and `Token.termLength()` directly instead. If you really need a String, use `Token.term()`
