在ElasticSearch 5.6中，我创建了相同15k文档的多个索引。具体来说，4都共享相同的映射，设置和内容。
4中有3个的索引大小约为1.0 GB。 4中index_1的大小为52 MB。我对4个索引中的搜索进行了比较，index_1返回的文档数量少于其他文档的相同搜索量。我已经看到每个查询的文档数量减少了1％到80％。
此时，我不相信docs.count或其他store.size_in_bytes上的index_1或GET index_1, index_2, index_3, index_4/_stats/docs,store。这让我处于这样一种情况：我正在创建多个索引只是为了得到一个可靠的答案。
为什么其中一个指数与其他指数如此偏离？
