使用弹性搜索我试图添加一个计算的distance字段到地理搜索。我只想在搜索文档中附加一个额外的计算字段，但是当我通过“script_fields”添加计算字段时，则仅返回该字段。
我尝试添加通配符字段部分，但它并没有影响结果。
如何让这个查询返回complete documents添加了额外的计算字段？
GET /ocsm_test/inventory/_search
{
"query": {
"bool": {
"must": {
"match_all": {}
},
"filter": {
"geo_distance": {
"distance": "2km",
"address.geo.location": [],
"loc.address.geo.location": [
151.2165507,
-33.8732887
]
}
}
}
},

},

}
},
"fields": [
".*"
],
"post_filter": {
"bool": {
"must": [

}

}
}
}
检索字段 https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-fields.html不推荐，你应该使用源过滤 https://www.elastic.co/guide/en/elasticsearch/reference/current/search-request-source-filtering.html反而。
所以，而不是这个
"fields": [
".*"
],
用这个：
"_source": true
