Spring Data ElasticSearch - Index single field multiple times

Question

I want to index a single field (name) multiple times with different analyzers (ngram and standard) so that I can search using partial words or full words. But I could not find Spring Data ElasticSearch's support for this. Since @Field annotation can not be repeated, so how can I achieve this using Spring Data?

import org.springframework.data.elasticsearch.annotations.InnerField;
   import org.springframework.data.elasticsearch.annotations.MultiField;

        @MultiField(
                  mainField = @Field(type = FieldType.String),
                  otherFields = {
                      @InnerField(index = FieldIndex.not_analyzed, suffix = "<suffix name>", type =FieldType.String)
                  }
                )
        private String <fieldname>;

This way you can store the same field multiple times with different analyzers, please remember to use the meaningful suffix name for searching that field
