es报错Fielddata

skuinfo --------数据库名 即index
docs------------表名 及 type
nativeSearchQueryBuilder.addAggregation(AggregationBuilders.terms("skuCategorygroup").field("categoryName.keyword").size(100));
nativeSearchQueryBuilder.addAggregation(AggregationBuilders.terms("skuBrandgroup").field("brandName.keyword").size(100));

报错：

Fielddata is disabled on text fields by default. Set fielddata=true on [tags] in order to load fielddata in memory by uninverting the inverted index.
