弹性搜索:限制数组中的搜索结果
Elastic Search : Restricting the search result in array

有什么方法可以将我的结果限制为仅包含地址 = Omega Residency 的对象,而不是其他具有地址 = Collage of Engineering 的对象?
您只能使用 nested
查询和 inner_hits
来完成。我看到您有 include_in_parent: true
但没有使用 nested
查询。如果您只想获取匹配的嵌套对象,则需要使用 nested
查询中的 inner_hits
:
GET /never/_search?pretty
{
"_source": false,
"query": {
"nested": {
"path": "Residence_address",
"query": {
"match": {
"Residence_address.address": "Omega Residency"
}
},
"inner_hits" : {}
}
