Question

全文索引搜索功能在cloudant中无效。

文件1：

{
  "_id": "527c8d9327c6f27f17df0d2e17000530",
  "_rev": "9-4a61c6dac8d03a7d55696c3dde6a4f50",
  "employee_ID": "SCI130202",
  "proj_role": "Team Member",
  "work_total_experience": "4",
}

文件2：

{

  "_id": "527c8d9327c6f27f17df0d2e17000531",
  "_rev": "9-4a61c6dac8d03a7d55696c3dd46a4f50",
  "employee_ID": "SCI130201",
  "proj_role": "developer",
  "work_total_experience": "2",
}

索引功能：

{ 
 "_id": "_design/search_emp",
 "_rev": "3-4562324d684a2f13d2a1f6f570736e7e",
 "views": {},
 "language": "javascript",
 "indexes": {
    "by_employee": {
      "analyzer": "standard",
      "index": "function(doc){index(doc.proj_role,{'field':'project_role'})index(doc.work_total_experience,{'field':'work_experience'})}"
    }}}

如果我传递的网址如：https://{username}.cloudant.com/databasename/_design/search_emp/_search/by_employee?q=project_role:developer & work_experience:2

这仅适用于一种情况，但我需要获得具有2年经验详情的确切输出开发人员。

Answer 1

所以这里有两个问题，一个是你如何定义索引，一个是你如何查询它。

你正在调用index(doc.proj_role,{'field':'project_role'});，但我不确定这是正确的语法;我相信你想：index("project_role", doc.proj_role);
两个条件之间的&应为AND：q=project_role:developer AND work_experience:2

希望有所帮助。

Answer 2

这对我有用......

这是我的设计文档：

{
    "doc": {
        "_id": "_design/search_emp",
        "_rev": "17-e7f119c21ca21cc6ac44c5a967cd5550",
        "indexes": {
            "by_employee": {
                "analyzer": "standard",
                "index": "function(doc) {\n    index('project_role', doc.proj_role, {});\n    index('work_experience', doc.work_total_experience, {});\n}"
            }
        },
        "language": "javascript",
        "views": {}
    },
    "id": "_design/search_emp",
    "key": "_design/search_emp",
    "value": {
        "rev": "17-e7f119c21ca21cc6ac44c5a967cd5550"
    }
}

网址：

https://username.cloudant.com/databasename/_design/search_emp/_search/by_employee?include_docs=true&q=work_experience:%222%22%20AND%20project_role:developer

注意：我必须在经验值周围加上双引号。 work_experience:"2"为我工作，但work_experience:2无效。

回应：

{

                "_rev": "1-795df1c239d3d029eaa6d8c45ef70a8c",
                "employee_ID": "SCI130201",
                "proj_role": "developer",
                "work_total_experience": "2"
            },
            "fields": {},
            "id": "90958a20a020a7483d3311a156fcf571",
            "order": [
                0.4339554011821747,
                0
            ]
        }
    ],
    "total_rows": 1
}

全文索引在cloudant中不起作用
