我对此感到困惑
我在弹性中定义了以下字段
"Email": {
"type": "text",
"boost": 0,
"index": false,
"analyzer": "standard"
}
但是，当我搜索记录时，我得到的记录仅与包含以下突出显示语句的该字段匹配
"highlight": {
"properties.Email": [
"<mark>someone</mark>@somewhere.com"
]
}
我的理解是index：false应该阻止该字段可搜索，并且如果该字段不可搜索，则不应将其包含在突出显示的结果中
我的理解是错误的还是其他地方有问题
编辑：需要更多信息 要求完整的映射 原始数据是GeoJson

已请求搜索逻辑，因此请在此处添加
我正在使用PHP界面，但这是搜索查询
其中 $ q是用户提供的字符串 $ index是要搜索的索引
[
'index' => $index ,
'ignore_unavailable'=>true,
'size' => 20,
'body' => [
'query' => [
'bool' => [
'must' => [
"bool" => [
"should" => [
[
"match_phrase" => [
"_all" => [
"query" => $q,
"boost" => 8
]
]
],
[
"match" => [
"_all" => [
"query" => $q,
"operator"=> "and",
"boost" => 2
]
]
],
[
"match" => [
"_all" => [
"query" => $q,
"boost" => 1
]
]
],
[
"wildcard" => [
"_all" => [
"wildcard" => '*' . $q . '*',
"boost" => 0.5
]
]
]
]
]
]
]
],
'highlight' => [
'pre_tags' => ['<mark>'],
'post_tags' => ['</mark>'],
'fields' => [
'*' => [

]
]
]
]
];

这是一个Elasticsearch Internals主题。简而言之，该信息保留在_source中，由高亮显示。
更多细节。引用Mapping Parameters - index：
索引选项控制是否对字段值建立索引。它接受
true或false，默认为true。未索引的字段不可查询。
仅此而已。该值不会进入Apache Lucene的inverted index中，因此查询毫无意义。但是，该字段保留在_source中，并且仍可用于聚合。汇总示例：假设您想知道，特定邮件地址中存在多少个文档。
如果您不想将其用于聚合，则可以添加"enabled": false mapping parameter。
Highlighting是另一个概念。
如果未存储该字段（映射未将
store设置为true），则会加载实际的_source并从_source中提取相关字段。
简而言之，它访问_source字段。映射参数_source和index的信息保留在enabled中。在大多数情况下，这是强制性的。如果禁用源，则不能
