- Deprecated Methods
  Method and Description
  org.apache.lucene.index.IndexableField.boost() Index-time boosts are deprecated, please index index-time scoring factors into a doc value field and combine them with the score at query time using eg. FunctionScoreQuery.
  org.apache.lucene.search.FuzzyQuery.floatToEdits(float, int) pass integer edit distances instead.
  org.apache.lucene.index.IndexWriter.getCommitData() Use `IndexWriter.getLiveCommitData()` instead.
  org.apache.lucene.util.CharsRef.getUTF16SortedAsUTF8Comparator() This comparator is only a transition mechanism
  org.apache.lucene.util.SloppyMath.haversinKilometers(double, double, double, double) Use `instead`
  org.apache.lucene.index.IndexWriter.isLocked(Directory) Use of this method can only lead to race conditions. Try to actually obtain a lock instead.
  org.apache.lucene.document.FieldType.numericPrecisionStep() Please switch to `PointValues` instead
  org.apache.lucene.document.FieldType.numericType() Please switch to `PointValues` instead
  org.apache.lucene.store.DataInput.readStringSet() Only for reading existing formats. Encode maps with `DataOutput.writeSetOfStrings(Set)` instead.
  org.apache.lucene.store.DataInput.readStringStringMap() Only for reading existing formats. Encode maps with `DataOutput.writeMapOfStrings(Map)` instead.
  org.apache.lucene.store.Directory.renameFile(String, String) Use `Directory.rename(java.lang.String, java.lang.String)` and `Directory.syncMetaData()` instead.
  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.document.Field.setBoost(float) Index-time boosts are deprecated, please index index-time scoring factors into a doc value field and combine them with the score at query time using eg. FunctionScoreQuery.
  org.apache.lucene.index.IndexWriter.setCommitData(Map<String, String>) Use `IndexWriter.setLiveCommitData(java.lang.Iterable<java.util.Map.Entry<java.lang.String, java.lang.String>>)` instead.
  org.apache.lucene.document.FieldType.setNumericPrecisionStep(int) Please switch to `PointValues` instead
  org.apache.lucene.document.FieldType.setNumericType(FieldType.LegacyNumericType) Please switch to `PointValues` instead
  org.apache.lucene.search.Explanation.toHtml()
