如何使用 QueryElevationComponent 改进搜索结果? [英] How to improve search results with QueryElevationComponent?

问题描述

我正在使用 solr 1.4 并使用 QueryElevation 组件来保证搜索位置.我有大约 700,000 个带有 1 Mb 高程文件的文档.结果在newrelic监控网站上很慢:

I'm using solr 1.4 and using QueryElevation Component for guaranteed search position. I have around 700,000 documents with 1 Mb elevation file. It turns out it is quite slow on the newrelic monitoring website:

Slowest Components                                       Count   Exclusive           Total    
QueryElevationComponent                                1    506,858 ms 100% 506,858 ms 100%
SolrIndexSearcher                                        1    2.0 ms    0%    2.0 ms    0%

QueryComponent                                            1    1.0 ms    0%   1.0 ms    0%
DebugComponent                                            1    0.0 ms    0%    0.0 ms    0%

我正在寻找如何提高搜索查询的速度.这QueryElevation 组件花费太多时间不可接受.海拔文件的大小仅为 1 Mb.我想知道其他使用这个组件的人没有问题(与速度有关)?我是吗用错了方法或者这个组件的使用有限制?

I'm looking for how to improve the speed of the search query. The QueryElevation Component is taking too much time which is unacceptable. The size of elevation file is only 1 Mb. I wonder other people using this component without problems (related to speed)? Am I using it the wrong way or there is a limit when using this component?

推荐答案

您想要提升的文档数量非常庞大 - 我确定这不是为此而设计的 :-)！

This is a huge number of docs you want to elevate - I'm sure this wasn't designed for that :-)!

您的文档是否有共同的属性，例如salesrank，然后您可以简单地使用 dismax 处理程序来提升文档?例如通过 bf=recip(sqrt(sales_rank_i),1,1,1))

Isn't there a common attribute of your docs e.g. salesrank, where you can then simply use the dismax handler to boost the docs? e.g. via bf=recip(sqrt(sales_rank_i),1,1,1))

(或者您可以简单地根据这个 salesrank 字段对文档进行排序)

(Or you could simply sort the docs against this salesrank field)

或者你不能介绍一个这样的领域吗?

Or couldn't you introduce such a field?
