如何管理“分页"与索尔? [英] How to manage "paging" with Solr?

问题描述

我有一个分类广告网站...我让 Solr 搜索分类广告，然后返回 ID:nrs，然后我将其放入一个数组中.然后我使用这个数组在 MySql 数据库中查找任何分类，其中 ID:s 与 Solr 返回的数组中的 ID:s 匹配.

I have a classifieds website... I have Solr doing the searching of the classifieds, and then return ID:nrs which I then use to put into an array. Then I use this array to find any classifieds in a MySql db where the ID:s match the ID:s in the array returned by Solr.

现在，因为这个数组可能非常大(10 万条记录或更多)，所以我需要分页"结果，以便一次返回 100 个.然后在 MySql 中使用这 100 个 ID:s 来查找分类信息.

Now, because this array can be very very big (100thousand records or more) then I would need to "page" the results so that maybe 100 where returned at a time. And then use those 100 ID:s in MySql to find the classifieds.

那么，是否可以使用 SOLR 进行分页?

So, is it possible to page with SOLR?

如果是这样，怎么办?我需要示例代码...结果会是什么.

And if so, how? I need example code... And what the results would be please.

主要是我需要一个完整的例子！

Mostly I need a thorough example!

谢谢

推荐答案

看看 IBM.也许这会让你走上正确的道路.

Take a look at IBM. Maybe that will get you on the right course.

结果数:指定返回的最大结果数.

Number of results: Specifies the maximum number of results to return.

Start:结果集中开始的偏移量.这对于分页很有用.

Start: The offset to start at in the result set. This is useful for pagination.

所以你可能想要一些变化

So you probably want some variation on

<str name="rows">10</str>
<str name="start">0</str>

您的 solr 客户端应该提供一些方法来轻松获得结果总数.

Your solr client should provide some way to get the total number of results without much trouble.
