elasticsearch\Command updateAnalyzers()

Define new analyzers for the index.

For example if content analyzer hasn’t been defined on "myindex" yet you can use the following commands to add it:

 $setting = [
     'analysis' => [
         'analyzer' => [
             'ngram_analyzer_with_filter' => [
                 'tokenizer' => 'ngram_tokenizer',
                 'filter' => 'lowercase, snowball'
             ],
         ],
         'tokenizer' => [
             'ngram_tokenizer' => [
                 'type' => 'nGram',
                 'min_gram' => 3,
                 'max_gram' => 10,
                 'token_chars' => ['letter', 'digit', 'whitespace', 'punctuation', 'symbol']
             ],
         ],
     ]
];
$elasticQuery->createCommand()->updateAnalyzers('myindex', $setting);
