我使用elasticsearch 2.2.0并创建数据映射如下：

如何从映射中删除排除字段（如下所示）：
"_source": { "excludes" : ["fileAttachment.fileContent", "fileAttachmentFr.fileContent", "fileAttachmentEn.fileContent", "contentBody", "contentBodyFr", "contentBodyEn", "geoLocations.boundaries"] }
我不想重新索引我的数据，因为它需要一整天才能完成。 请帮助：）
答案 0 :(得分：1)
如果不重新编制索引，就无法更改ElasticSearch映射。
但是，您可以查看https://www.elastic.co/blog/changing-mapping-with-zero-downtime
显示了如何以几乎零停机时间重新编制索引
