ElasticSearch - 在嵌套字段上進行全文本搜索

Question

如果有人可以提供幫助嗎？ 1.全文搜索查詢，其中標題和描述都是頂級域

GET /docidx/Document/_search 
{ 
    "query": { 
     "query_string": { 
      "query": "title:computer AND description:electronics" 
     } 
    } 
} 

This works fine. 

2. The full text search query where title is top level field but "abstract.content" i.e content is a nested field under abstract - does not return results. 

GET /docidx/Document/_search 
{ 
    "query": { 
     "query_string": { 
      "query": "title:computer AND abstract.content:memory" 
     } 
    } 
} 

Does Elastic Search has support for full text search for nested fields? 

Answer 1

使用must和nested Query組合：

GET /docidx/Document/_search 
{ 
"query": { 
    "bool": { 
    "must": [ 
     { 
      "query_string": { 
       "default_field": "title", 
       "query": "computer" 
      } 
     }, 
     { 
      "nested": { 
       "path": "abstract", 
       "query": { 
       "query_string": { 
        "default_field": "abstract.content", 
        "query": "memory" 
       } 
       } 
      } 
      } 
     ] 
     } 
    } 
    }
