Deprecated Classes

Class and Description
org.apache.lucene.analysis.miscellaneous.FixBrokenOffsetsFilter Fix the token filters that create broken offsets in the first place.
org.apache.lucene.analysis.core.LowerCaseTokenizer Use LetterTokenizer followed by LowerCaseFilter
org.apache.lucene.analysis.core.LowerCaseTokenizerFactory Use LetterTokenizerFactory followed by LowerCaseFilterFactory
org.apache.lucene.analysis.standard.StandardFilterFactory StandardFilter is a no-op and can be removed from filter chains
org.apache.lucene.analysis.synonym.SynonymFilter Use SynonymGraphFilter instead, but be sure to also use FlattenGraphFilter at index time (not at search time) as well.
org.apache.lucene.analysis.synonym.SynonymFilterFactory Use SynonymGraphFilterFactory instead, but be sure to also use FlattenGraphFilterFactory at index time (not at search time) as well.
org.apache.lucene.analysis.miscellaneous.WordDelimiterFilter Use WordDelimiterGraphFilter instead: it produces a correct token graph so that e.g. PhraseQuery works correctly when it's used in the search time analyzer.
org.apache.lucene.analysis.miscellaneous.WordDelimiterFilterFactory Use WordDelimiterGraphFilterFactory instead: it produces a correct token graph so that e.g. PhraseQuery works correctly when it's used in the search time analyzer.

Deprecated Fields

Field and Description
org.apache.lucene.analysis.ngram.EdgeNGramTokenFilter.DEFAULT_MAX_GRAM_SIZE since 7.4 - this value will be required.
org.apache.lucene.analysis.ngram.NGramTokenFilter.DEFAULT_MAX_NGRAM_SIZE since 7.4 - this value will be required.
org.apache.lucene.analysis.ngram.EdgeNGramTokenFilter.DEFAULT_MIN_GRAM_SIZE since 7.4 - this value will be required.
org.apache.lucene.analysis.ngram.NGramTokenFilter.DEFAULT_MIN_NGRAM_SIZE since 7.4 - this value will be required.
org.apache.lucene.analysis.core.StopAnalyzer.ENGLISH_STOP_WORDS_SET

Deprecated Methods

Method and Description
org.apache.lucene.analysis.util.CharTokenizer.fromSeparatorCharPredicate(AttributeFactory, IntPredicate, IntUnaryOperator) Normalization should be done in a subsequent TokenFilter
org.apache.lucene.analysis.util.CharTokenizer.fromSeparatorCharPredicate(IntPredicate, IntUnaryOperator) Normalization should be done in a subsequent TokenFilter
org.apache.lucene.analysis.util.CharTokenizer.fromTokenCharPredicate(AttributeFactory, IntPredicate, IntUnaryOperator) Normalization should be done in a subsequent TokenFilter
org.apache.lucene.analysis.util.CharTokenizer.fromTokenCharPredicate(IntPredicate, IntUnaryOperator) Normalization should be done in a subsequent TokenFilter
org.apache.lucene.analysis.util.CharTokenizer.normalize(int) Normalization should be done in a subsequent TokenFilter

Deprecated Constructors

Constructor and Description
org.apache.lucene.analysis.util.ClasspathResourceLoader() You should not use this ctor, because it uses the thread's context class loader, which is bad programming style. Please specify a reference class or a ClassLoader instead.
org.apache.lucene.analysis.ngram.EdgeNGramTokenFilter(TokenStream, int, int) since 7.4. Use EdgeNGramTokenFilter.EdgeNGramTokenFilter(TokenStream, int, int, boolean) instead.
org.apache.lucene.analysis.util.FilesystemResourceLoader(Path) You should not use this ctor, because it uses the thread's context class loader as fallback for resource lookups, which is bad programming style. Please specify a ClassLoader instead.
org.apache.lucene.analysis.ngram.NGramTokenFilter(TokenStream) since 7.4. Use NGramTokenFilter.NGramTokenFilter(TokenStream, int, int, boolean) instead.
org.apache.lucene.analysis.ngram.NGramTokenFilter(TokenStream, int, int) since 7.4. Use NGramTokenFilter.NGramTokenFilter(TokenStream, int, int, boolean) instead.
org.apache.lucene.analysis.core.StopAnalyzer() Use a constructor with a specific stop word set
