Question

我们有大量的功能过滤查询被推入主查询（q参数）。我担心这些额外的部分会得到不必要的评分。但是我们确实指定了一种排序，并且分数不包括在排序中。所以我的问题是搜索是否得分，因为最终它没有按分数排序？

Answer 1

基于“说明”日志，即使在字段上指定排序参数，它看起来也会得分。

这是我在没有排序参数的情况下观察到的“解释”日志，（结果按分数排序）：

http://localhost:8983/solr/logmill/select?q=text_en%3A%22not+found%22&wt=xml&indent=true&debugQuery=true


<lst name="explain">

</str>
</lst>
</lst>

以下是使用sort param查询的“explain”日志，（结果按timestamp_tdt字段排序）：

即使我在解释日志中指定＆amp; sort = timestamp_tdt％20asc，我也看到它正在计算草皮和分数的乘积等。希望这有助于找到问题的答案。

Solr：如果指定了sort参数，文档是否得分？
