Overview

Stores ElasticSearch index settings and resolves ‘analysis` hash. At first, you need to store some analyzers or other analysis options to the corresponding repository:

Chewy.analyzer :title_analyzer, type: 'custom', filter: %w(lowercase icu_folding title_nysiis)
Chewy.filter :title_nysiis, type: 'phonetic', encoder: 'nysiis', replace: false

‘title_nysiis` filter here will be expanded automatically when `title_analyzer` analyser will be used in index settings:

class ProductsIndex < Chewy::Index
  settings analysis: {
    analyzer: [
      'title_analyzer',
      {one_more_analyzer: {type: 'custom', tokenizer: 'lowercase'}}
    ]
  }
end

Additional analysing options, which wasn’t stored in repositories, might be used as well.
