问题描述

Arango 中的数据:

Data in Arango:

{
 "employees": [
    {
      "lastName": "Ansari",
      "firstName": "Haseb"
    },
    {
      "lastName": "Ansari",
      "firstName": "Affan"
    },
    {
      "lastName": "Keshav",
      "firstName": "Anil"
    }
  ],

索引:POST http://localhost:8529/_db/db_test/_api/index?collection=测试

身体:

 "type" : "fulltext", 
 "fields" : [ 
   "lastName" 
  ] 
}

搜索:

PUT http://localhost:8529/_db/db_test/_api/simple/fulltext

身体:

{ 
  "collection" : "test", 
  "attribute" : "lastName", 
  "query" : "Ansari" 
}

我希望在我的应用程序中使用 REST API 进行全文搜索.请帮助我在这里出错的地方.例如，这是 arango 商店中的一份文件.否则，我将拥有更多文档，因此进行全文搜索.

I want in my application to use REST API for full text search. Please help me where I am going wrong here. And this is one document in arango store just for example. Otherwise, i'll be having more documents hence full-text search.

推荐答案

简短:您的索引不在文档的某个字段上.

Short: Your index is not on a field in your document.

长:您正在保存一个文档，它有一个列表 employees，但没有文档 lastname - 那在 employees 里面，但这与路径.

Long: You're saving one document, it has a list employees, but no document lastname - thats inside of employees but this won't match the path.

然而，如果您将全文索引放在employees 上，则可以使其工作，然后对象employees 的所有属性都将被索引.但是，您将匹配名字的和姓氏.

You can however make it work if you put the fulltext index on employees, then all attributes of the object employees will be indexed. You then however will match on first and last name.

如果你想单独做这个，你需要直接匹配这样的令牌:employees[0].lastName

If you want to do this separate, you need to directly match a token like that: employees[0].lastName
