它在FQL 用户文档中说有 4 个可索引字段(标有 *):
- 姓名
- 第三方ID
- uid
- 用户名
但是当我执行这样的查询时:
SELECT uid
FROM user
WHERE name = "Mark Zuckerberg"
我收到一个错误:
{
"error": {
"message": "Your statement is not indexable. The WHERE clause must contain
an indexable column. Such columns are marked with * in the
tables linked from
http://developers.facebook.com/docs/reference/fql ",
"type": "NoIndexFunctionException",
"code": 604
}
}
我在这里想念什么?这是一个错误吗?如何按名称过滤用户表上的 FQL 查询?
