你需要使用Nested DataType,对应的你需要使用Nested Query
您在当前模型中拥有的似乎是basic object model。
我在下面提到了示例映射、示例文档、嵌套查询和响应。这将为您提供所需的内容。
映射
PUT resumes
{
"mappings": {
"mydocs": {
"properties": {
"skills": {
"type": "nested",
"properties": {
"skill": {
"type": "keyword"
},
"years": {
"type": "integer"
}
}
}
}
}
}
}
示例文件:
POST resumes/mydocs/1
{
"skills": [
{
"skill": "python",
"years": 3
},
{
"skill": "java",
"years": 3
}
]
}
POST resumes/mydocs/2
{
"skills": [
{
"skill": "python",
"years": 2
},
{
"skill": "java",
"years": 3
}
]
}
查询
POST resumes/_search
{
"query": {
"nested": {
"path": "skills",
"query": {
"bool": {
"must": [
{
"match": {
"skills.skill": "python"
}
},
{
"match": {
"skills.years": 3
}
}
]
}
}
}
}
}
查询响应:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1.6931472,
"hits": [
{
"_index": "resumes",
"_type": "mydocs",
"_id": "1",
"_score": 1.6931472,
"_source": {
"skills": [
{
"skill": "python",
"years": 3
},
{
"skill": "java",
"years": 3
}
]
}
}
]
}
}
请注意,您仅在上述响应中检索 id 为 1 的文档。另请注意,为了简单起见,我将 Skills.skill 设为 keyword 类型。您可以根据您的用例将其更改为 text。
希望对你有帮助!
