terms聚合,添加子聚合bucketSortAggregation,因为我们已经知道需要的页数和条数,所以这个地方的size我们不必设置为较大的默认值,而是当前页数的最后一条记录,为(page - 1) * size + size = page * size TermsAggregationBuildertermsAggregationBuilder=terms(chapterTermsAggName).field("extern.paragraph_id").size(p...

1、terms聚集 terms聚集根据文档字段中的词项做分桶,所有包含同一词项的文档将被归 人同一桶中,聚集结果中包含字段中的词项及其词频,在默认情况下还会根据词 频排序,所以terms聚集也可用于热词展示,由于terms聚集在统计词项的词频数据时需要打开它的fielddata机制。fielddata机制对内存消耗较大且有导致内存溢出的可能,所以...
