從elasticsearch獲取沒有任何矢量結果嗎？

Question

我跟着https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-termvectors.html但是無法得到預期的結果。我做錯了哪一部分？

文件的格式是：

PUT integrity 
{ 
    "mappings": { 
    "body": { 
     "properties": { 
     "label": { 
      "type": "keyword", 
      "index": "not_analyzed", 
      "store": true 
     }, 
     "body": { 
      "type": "text", 
      "store": true 
     } 
     } 
    } 
    } 
} 

Answer 1

的_all字段的默認映射不包括存儲詞向量：

"_all": { 
     "full_name": "_all", 
     "mapping": { 
     "_all": { 
      "enabled": true, 
      "store": false, 
      "store_term_vectors": false, 
      "store_term_vector_offsets": false, 
      "store_term_vector_positions": false, 
      "store_term_vector_payloads": false, 
      "norms": true, 
      "analyzer": "default", 
      "similarity": "BM25" 
     } 
     } 
    } 

和，也似乎_all場有點特別，Elasticsearch不是compute the vectors on the fly。

你只爲_all選擇是它能夠長期向量：

PUT integrity 
{ 
    "mappings": { 
    "body": { 
     "_all": { 
     "term_vector": "with_positions_offsets" 
     }, 
     "properties": { 
     "label": { 
      "type": "keyword", 
      "index": "not_analyzed", 
      "store": true 
     }, 
     "body": { 
      "type": "text", 
      "store": true 
     } 
     } 
    } 
    } 
}
