   == Kölner Phonetik a.k.a. Cologne Phonetic
   
  -To use this encoding in your analyzer, specify `encoding="ColognePhonetic"` with the <<filter-descriptions.adoc#phonetic-filter,Phonetic Filter>>.
  +To use this encoding in your analyzer, specify `encoder="ColognePhonetic"` with the <<filter-descriptions.adoc#phonetic-filter,Phonetic Filter>>.
   
   The Kölner Phonetik, an algorithm published by Hans Joachim Postel in 1969, is optimized for the German language.

  == Refined Soundex
  
  To use this encoding in your analyzer, specify `encoding="RefinedSoundex"` with the <<filter-descriptions.adoc#phonetic-filter,Phonetic Filter>>.
  
  Encodes tokens using an improved version of the Soundex algorithm.

  == Double Metaphone
  
  To use this encoding in your analyzer, see <<filter-descriptions.adoc#double-metaphone-filter,Double Metaphone Filter>> in the Filter Descriptions section. Alternatively, you may specify `encoder="DoubleMetaphone"` with the <<filter-descriptions.adoc#phonetic-filter,Phonetic Filter>>, but note that the Phonetic Filter version will *not* provide the second ("alternate") encoding that is generated by the Double Metaphone Filter for some tokens.
  
  Encodes tokens using the double metaphone algorithm by Lawrence Philips. See the original article at http://www.drdobbs.com/the-double-metaphone-search-algorithm/184401251?pgno=2
  
  == Metaphone
