在 vespa 中实现自定义搜索器

Question

我在Vespa中使用Searcher类的实现创建了基本搜索应用程序。我使用我的应用程序一一提供了以下文档。

{
"fields": {
"album": "Good",
"artist": "Arijit",
"title": "tum ho",
"year": 2017,
"duration": 300
}
}
{
"fields": {
"album": "Good",
"artist": "Atif",
"title": "bewajah",
"year": 2017,
"duration": 300
}
}
{
"fields": {
"album": "bad",
"artist": "Neha",
"title": "tere",
"year": 2017,
"duration": 400
}
}

我的搜索器类如下：

public class ExampleSearcher extends Searcher {
@Override
public Result search(Query query, Execution execution) {
retrun execution.search(query); 
}
}

现在，当我使用 API 进行搜索时：

http://localhost:8080/search/?album=good OR http://localhost:8080/search/?=good

我得到了结果：

{
"root": {
"id": "toplevel",
"relevance": 1,
"fields": {
"totalCount": 0
}
}
}

但是我应该得到这个结果输出：

{
"root": {
"id": "toplevel",
"relevance": 1,
"fields": {
"totalCount": 2
},
"children": [{
"id": "good",
"relevance": 1,
"fields": {
"album": "Good",
"artist": "Arijit",
"title": "tum ho",
"year": 2017,
"duration": 300
}
}, {
"id": "good",
"relevance": 1,
"fields": {
"album": "Good",
"artist": "Atif",
"title": "bewajah",
"year": 2017,
"duration": 300
}
}]
}
}

我做错了什么或我应该怎么做？

要实际搜索内容节点，而不是像示例中那样仅仅模拟 Hello world 结果，您需要将"inherits=vespa"添加到服务中的搜索链配置中.xml。
