如何使用 IndexTank 获取结果？

Question

我将 IndexTank 与 Java 客户端一起使用，但我似乎无法访问结果：

    SearchResults results = index.search(Query.forString(keywords));

    for (Map<String, Object> document : results.results) {
        System.out.println("doc id: " + document.get("docid"));

最后一行失败并显示： 类型不匹配：无法从对象转换为字符串

有谁知道为什么我会收到此错误？谢谢。

你所拥有的看起来不错。您确定导入了所有正确的类吗？这对我有用：

import java.util.HashMap;
import java.util.Map;

import com.flaptor.indextank.apiclient.Index;
import com.flaptor.indextank.apiclient.IndexTankClient;
import com.flaptor.indextank.apiclient.IndexTankClient.Query;
import com.flaptor.indextank.apiclient.IndexTankClient.SearchResults;

public class IndexTankExample {
    public static void main(String[] args) throws Exception {
        IndexTankClient client = new IndexTankClient("<PRIVATE URL>");
        Index index = client.getIndex("test");

        Map<String, String> fields = new HashMap<String, String>();
        fields.put("text", "foo bar baz");
        index.addDocument("1", fields);

        SearchResults results = index.search(Query.forString("bar"));
        for (Map<String, Object> document : results.results) {
            System.out.println("doc id: " + document.get("docid"));
        }
    }
}
