Methods

Method	Description
org.apache.lucene.index.IndexWriter.getFieldNames()
org.apache.lucene.search.FuzzyQuery.floatToEdits(float, int)	pass integer edit distances instead.
org.apache.lucene.search.IndexSearcher.termStatistics(Term, TermStates)	in favor of IndexSearcher.termStatistics(Term, int, long).
org.apache.lucene.search.Weight.extractTerms(Set<Term>)	Use Query.visit(QueryVisitor) with QueryVisitor.termCollector(Set)
org.apache.lucene.util.CharsRef.getUTF16SortedAsUTF8Comparator()	This comparator is only a transition mechanism
org.apache.lucene.util.fst.Util.getByOutput(FST<Long>, long)
org.apache.lucene.util.IOUtils.reThrow(Throwable)	This method is deprecated in favor of IOUtils.rethrowAlways(java.lang.Throwable). Code should be updated to IOUtils.rethrowAlways(java.lang.Throwable) and guarded with an additional null-argument check (because IOUtils.rethrowAlways(java.lang.Throwable) is not accepting null arguments).
org.apache.lucene.util.IOUtils.reThrowUnchecked(Throwable)	This method is deprecated in favor of IOUtils.rethrowAlways(java.lang.Throwable). Code should be updated to IOUtils.rethrowAlways(java.lang.Throwable) and guarded with an additional null-argument check (because IOUtils.rethrowAlways(java.lang.Throwable) is not accepting null arguments).
org.apache.lucene.util.SloppyMath.haversinKilometers(double, double, double, double)	Use instead
org.apache.lucene.util.SloppyMath.toDegrees(double)	Use Math.toDegrees(double) on Java 9+.
org.apache.lucene.util.SloppyMath.toRadians(double)	Use Math.toRadians(double) on Java 9+.
