映射不是创建
请解释猫鼬的配置。
我正在使用Express JS和MongoDb作为后端。
在 if 呼叫搜索 API 之后,我得到:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 0,
"max_score": null,
"hits": []
}
}
命中数组为空,总数为零,映射也显示为空。
4.3 + Elasticsearch 6.2 后遇到了同样的问题,这个问题是由于 Mongoosastic 与 Elasticsearch 6.x 不兼容!!
如果你用谷歌搜索,你会发现Elasticsearch将默认类型从"字符串"更改为"文本",并记录在这里。在帖子的末尾,他们说:
也就是说,您仍然应该考虑升级它们,因为我们计划在发布 Elasticsearch 6.0 时删除此向后兼容层。
我在Mongoosastic上发现了更多与最新Elasticsearch 6.2的不兼容性。 我已经提交了一个拉取请求来进行这些更改,但不确定何时/是否会被接受。在他们修复正式版本之前,我正在使用我的 Mongoosastic 克隆进行修复,直到他们修补官方存储库。
