我的文档有一个对象数组，每个对象都有一个值和一个置信度。 我想基于对象属性对返回的文档进行排序，但只对与查询具有匹配值的对象进行排序。
文档中包含属性标记＆＃39;包含如下数组：
[{"type":"imagga","value":"stone","confidence":16},
{"type":"imagga","value":"surface","confidence":13},
{"type":"imagga","value":"texture","confidence":25}]
我尝试在搜索中添加一个排序：
$searchParams['sort'] = [
"tags.confidence" => [
"order" => "desc",
"mode" => "min",
"nested_path" => "tags",
"nested_filter" => [
"term" => [
"tags.value" => "tree"
]
]
]
];
这不起作用。我的过滤器查询有效，并且只返回匹配的文档，但它们没有按原样排序。
我用这个作为一个例子，它看起来很相似，但没有用： https://www.elastic.co/guide/en/elasticsearch/guide/master/nested-sorting.html 和 http://w3facility.org/question/elasticsearch-sort-by-single-nested-document-key-in-array/
我还尝试将置信区域更改为not_analyzed，这没有任何区别，并确保它是一个长期的＆＃39;类型。
背景。我的文档代表大约10,000张图像，每个文档都有一个具有值和置信度的标记，因此用户可以根据文档中标记的置信度搜索某些内容并获取匹配的图像。
更新： 我的映射：
Array(
[_source] => Array(
[enabled] => 1
) [properties] => Array(
[fieldName] => Array(
[type] => geo_point
) [tags . value] => Array(
[type] => string[index] => not_analyzed
) [tags . confidence] => Array(
[type] => long[index] => not_analyzed
)
)
)
我的查询：
Array(
[sort] => Array(
[tags . confidence] => Array(
[order] => desc[mode] => min[nested_path] => tags[nested_filter] => Array(
