Tweaking the mapping

You can override/extend the elasticsearch settings by using the ELASTICSEARCH_EXTRA_SETTINGS setting

For example:

WAGTAILSEARCHEXTENSION_ELASTICSEARCH_EXTRA_SETTINGS = {
    'settings': {
        'analysis': {
            'analyzer': {
                'custom_analyzer': {
                  'type': 'custom',
                  'tokenizer': 'custom_tokenizer',
                  'filter': ['asciifolding', 'ngram']
                }
            },
            'tokenizer': {
                'custom_tokenizer': {
                    'type': 'nGram',
                    'min_gram': 3,
                    'max_gram': 15
                }
            }
        }
    }
}
