solr max分数解释
当我选择查看 solr 结果中的分数字段时，我会看到 solr 为每个返回的文档分配的分数以及 maxscore 值，该值是最上面返回的文档的分数。
我需要知道 solr 分数是否有限制。我的意思是，如果 maxscore 是 6.89343 或 2.34365，那么这是否意味着最终分数是 10 分之 6.89343 ？或者我如何确定我接近最正确的结果。
如果可能的话，我需要对 solr 使用的评分算法进行简单的解释。
When I choose to view the score field in solr results I see the score assigned by solr to every document returned and a maxscore value that is the score of the topmost returned document.
I need to know is there a cut-off to the solr score or not. I mean if the maxscore is 6.89343 or 2.34365, so does this mean that it is 6.89343 of 10 as the final score? or how can I decide that I'm close to the most correct result.
If possible, I need a simple explanation of the scoring algorithm used by solr.

maxscore 是搜索结果中最上面的文档的评分。
maxscore 没有截止值，取决于 Lucene/Solr 完成的评分计算和标准化。
最上面的文档将具有最大分数，而您可以从它下面的文档的分数中了解它们与最上面的文档的差距。

The maxscore is the scoring of the topmost document in the search results.
There is no cutoff for the maxscore, and depends upon the scoring calculations and normalization done by Lucene/Solr.
The topmost document would have the maxscore, while you would get an idea from the scores of the documents below it, as to how off they are from the topmost.

如果它确实是正态分布的 z 分数，那么您可以计算 CDF（如图所示 此处）。 CDF 将为您提供从 0 到 1 的有界分数。鉴于非标准化分数是通过几个步骤计算的，我很难解释 CDF 在这种情况下的真正含义，但您可以将其视为概率只要您的收藏中充满了相关材料，您就得到了正确的答案。
If it is indeed a z-score from a normal distribution then you can calculate the CDF (as it appears here ). The CDF will give you a bounded score from 0 to 1. Its hard for me to interpret what the CDF really means in this case given the un-normalized score is calculated in several steps, but you can sort of think of it as the probability that you got the right answer as long as your collection is well populated with the relevant material.
