云搜索查询索引函数

Question

我找不到太多关于如何正确定义索引函数的文档，这样我就可以对我需要的信息进行全文搜索。

我使用了炼金术API在我的文档中添加了“实体”json。例如，我有一份文件，其内容如下：

"_id": "redacted",
"_rev": "redacted",
"session": "20152016",
"entities": [


    {
      "relevance": "0.797773",
      "count": "3",
      "type": "Organization",
      "text": "California Constitution"
    },
    {
      "relevance": "0.690092",
      "count": "1",
      "type": "Organization",
      "text": "Governors Highway Safety Association"
    }
]

我还没有找到任何代码片段，说明如何构造查看嵌套json的搜索索引函数。

我试图索引整个对象似乎是不正确的。这是完整的设计文件：

    {
  "_id": "_design/entities",
  "_rev": "redacted",
  "views": {},
  "language": "javascript",
  "indexes": {
    "entities": {
      "analyzer": "standard",
      "index": "function (doc) {\n  if (doc.entities.relevance > 0.5){\n      index(\"default\", doc.entities.text, {\"store\":\"yes\"});\n  }\n\n}"
    }
  }
}

并且搜索索引格式化得更清楚一些

function (doc) {
  if (doc.entities.relevance > 0.5){
      index("default", doc.entities.text, {"store":"yes"});
  }

}

按照下面的建议添加for循环很有意义。但是，我仍然不能返回任何结果。我的查询是"search/entities?q=Governors“

服务器响应是：{"total_rows":0，“书签”：“g2o”，“行”：[]}

Answer 1

"for..in“样式循环似乎不起作用。但是，我确实使用更标准的循环循环来获得结果。

function (doc) {
  if(doc.entities){
    var arrayLength = doc.entities.length;
    for (var i = 0; i < arrayLength; i++) {
    if (parseFloat(doc.entities[i].relevance) > 0.5)
    index("default", doc.entities[i].text);
}
}
}

干杯!

Answer 2

您需要对doc.entities数组中的元素进行循环。

function (doc) {
  for(entity in doc.entities){
    if (parseFloat(entity.relevance) > 0.5){
      index("default", entity.text, {"store":"yes"});
    }
  }
}

Answer 3

这就是我试过的：

function(doc){
   if(doc.entities){
   for( var p in doc.entities ){
         if (doc.entities[p].relevance > 0.5)
          { 
             index("entitiestext", doc.entities[p].text, {"store":"yes"});
           }      
        }
     }
}

使用的查询字符串:"q=entitiestext:California Constitution&include_docs=true“结果：

{
"total_rows": 1,
"bookmark": "xxxx",
"rows": [
    {
        "id": "redacted",
        "order": [
            0.03693288564682007,
            1
        ],
        "fields": {
            "entitiestext": [
                "Governors Highway Safety Association",
                "California Constitution"
            ]
        },
        "doc": {
            "_id": "redacted",
            "_rev": "4-7f6e6db246abcf2f884dc0b91451272a",
            "session": "20152016",
            "entities": [
                {
                    "relevance": "0.797773",
                    "count": "3",
                    "type": "Organization",
                    "text": "California Constitution"
                },
                {
                    "relevance": "0.690092",
                    "count": "1",
                    "type": "Organization",
                    "text": "Governors Highway Safety Association"
                }
            ]
        }
    }
]

}

使用的查询字符串: q=entitiestext:California组合

结果：

 {
"total_rows": 1,
"bookmark": "xxxx",
"rows": [
    {
        "id": "redacted",
        "order": [
            0.03693288564682007,
            1
        ],
        "fields": {
            "entitiestext": [
                "Governors Highway Safety Association",
                "California Constitution"
            ]
        }
    }
]

}
