弹性 API 不会显示所有文档

Question

我有弹性，我想从弹性查询中获取数据，我在索引中有大约210个文档，但是当我试图用查询match_all进行搜索时，API只显示7个文档而不是所有文档，是否有可能API显示所有文档，而不是只显示一些文档。

查询:

192.168.20.47:9200/new/_search
{
"query" : {
"match_all" : {}
}
}

弹性API结果:

Answer 1

它返回10个结果(不是7个)。这是因为您没有指定size。

From the docs:

默认情况下，搜索返回前10个匹配命中。要浏览更大的结果集，可以使用搜索API的from和size参数。from参数定义要跳过的点击次数，默认为0。size参数是要返回的最大命中数。这两个参数一起定义了一个页面的结果。

那么，这就是您的查询在size最大值为10,000时的样子:

192.168.20.47:9200/new/_search
{
"query" : {
"match_all" : {}
},
"size" : 10000
}
