我有一个包含许多标签的用户文档这
是映射:
{
"user" : {
"properties" : {
"tags" : {
"type" : "nested",
"properties" : {
"id" : {
"type" : "string",
"index" : "not_analyzed",
"store" : "yes"
},
"current" : {
"type" : "boolean"
},
"type" : {
"type" : "string"
},
"value" : {
"type" : "multi_field",
"fields" : {
"value" : {
"type" : "string",
"analyzer" : "name_analyzer"
},
"value_untouched" : {
"type" : "string",
"index" : "not_analyzed",
"include_in_all" : false
}
}
}
}
}
}
}
}

使用上述 ES 文档进行搜索,我想构建一个查询,我需要在其中获取嵌套标签文档中具有公司标签的用户或没有任何公司标签的用户。我的搜索查询是什么?
例如在上面的例子中,如果搜索 google 标签,那么返回的文档应该是 'user 1' 和 'user 3' (因为用户 1 有公司标签 google 而用户 3 没有公司标签)。用户 2 没有返回,因为它也有 google 以外的公司标签。
