python - Google App EngineSearch API 中的分页

Question

我想在 google app engine search api 中使用游标(不偏移)进行分页。向前分页很简单，问题是如何实现向后分页。

Answer 1

我猜你在使用游标向后翻页时运气不好。

The Search API also supports the use of query cursors. Cursors are another way to indicate the point from which to begin a query, allowing you to continue a search from the end of the previous result set. Using a cursor is generally more efficient than using offsets. However, the Search API doesn't currently support a "reverse cursor" as does the Datastore API, making it more difficult to to implement backward paging. For this reason, the example application uses offsets rather than cursors to paginate its query results. You can find an example using cursors here.
