  +`max_inspections`::
       A factor that is used to multiply with the
       `shards_size` in order to inspect more candidate spell corrections on
       the shard level. Can improve accuracy at the cost of performance.

  +`min_doc_freq`::
       The minimal threshold in number of documents a
       suggestion should appear in. This can be specified as an absolute number
       or as a relative percentage of number of documents. This can improve
       quality by only suggesting high frequency terms. Defaults to 0f and is
       not enabled. If a value higher than 1 is specified then the number
       cannot be fractional. The shard level document frequencies are used for

       percentage number (e.g 0.4) or an absolute number to represent document

      performance. The shard level document frequencies are used for this

  doesn't take the query into account that is part of request.
  
  ==== Common suggest options:
  
  [horizontal]
  `text`::
      The suggest text. The suggest text is a required option that
      needs to be set globally or per suggestion.
  
  `field`::
      The field to fetch the candidate suggestions from. This is
      an required option that either needs to be set globally or per
      suggestion.
  
  `analyzer`::
      The analyzer to analyse the suggest text with. Defaults
      to the search analyzer of the suggest field.
  
  `size`::
      The maximum corrections to be returned per suggest text
      token.
  
  `sort`::
      Defines how suggestions should be sorted per suggest text
      term. Two possible values:
  +
      ** `score`:     Sort by score first, then document frequency and
                      then the term itself.
      ** `frequency`: Sort by document frequency first, then similarity
                      score and then the term itself.
  +
  `suggest_mode`::
      The suggest mode controls what suggestions are
      included or controls for what suggest text terms, suggestions should be
      suggested. Three possible values can be specified:
  +
       ** `missing`:  Only provide suggestions for suggest text terms that are
                      not in the index. This is the default.
       ** `popular`:  Only suggest suggestions that occur in more docs then
                      the original suggest text term.
       ** `always`:   Suggest any matching suggestions based on terms in the
                      suggest text.
  
  ==== Other term suggest options:
  
  [horizontal]
  `lowercase_terms`::
      Lower cases the suggest text terms after text analysis.
  
  `max_edits`::
      The maximum edit distance candidate suggestions can
      have in order to be considered as a suggestion. Can only be a value
      between 1 and 2. Any other value result in an bad request error being
      thrown. Defaults to 2.
  
  `prefix_length`::
      The number of minimal prefix characters that must
      match in order be a candidate suggestions. Defaults to 1. Increasing
      this number improves spellcheck performance. Usually misspellings don't
      occur in the beginning of terms. (Old name "prefix_len" is deprecated)
  
  `min_word_length`::
      The minimum length a suggest text term must have in
      order to be included. Defaults to 4. (Old name "min_word_len" is deprecated)
  
  `shard_size`::
      Sets the maximum number of suggestions to be retrieved
      from each individual shard. During the reduce phase only the top N
      suggestions are returned based on the `size` option. Defaults to the
