问HN：所有现代的元搜索引擎都很无趣吗？
似乎没有现代的元搜索引擎能够从其来源获取所有可用结果（通过分页），然后对这些结果进行爬取和重新排序。根据我从论文中了解到的，这正是原始元爬虫所做的。
我的问题是：你知道现代有哪种搜索引擎能做到这一点吗？除了元爬虫，你还记得其他旧的搜索引擎吗？
这可能会比较慢，但我认为这样的工具会非常棒，特别是如果它是开源的，这样我就可以提出并实验自己的排序方法。

It seems like there is no modern meta-search engine that gets all the available results (by paginating) from its sources, and then crawls them and re-ranks them. As far as I can tell from the paper, this is what the original meta-crawler did.<p>My questions: Do you know of any modern ones that do this? Do you remember any old ones that did this besides meta-crawler?<p>It might be slower, but I think that something like this would be fantastic, especially if it were open source so that I could come up with and experiment with my own ranking methods.
