Sql 选择按列和排序的两个查询的交集

我有以下三个表格：

documents (id, content) 
words (id, word) 
word_document (word_id, document_id, count)

Words表包含所有文档中出现的所有单词，word_文档将单词与文档关联，以及文档中该单词的计数

我想编写一个查询来搜索两个单词，并只返回两个单词都按文档中两个单词的总数排序的文档

比如说

DocA: green apple is not blue
DocB: blue apple is blue
DocC: red apple is red

现在搜索苹果和蓝色将返回：

DocA, 3
DocB, 2

因为：

DocA contains both words and 3 of them
DocB contains both words and 2 of them
DocC only contains one word

---

我成功地使用了intersect，但它没有返回计数和，也没有顺序

我认为这应该可以做到：

select a.document_id, a.count + b.count
from 
(
 select document_id, count
 from word_document
 where word_id = 'apple'
 group by document_id
) a 
INNER JOIN 
(
 select document_id, count
 from word_document
 where word_id = 'blue'
 group by document_id
) b 
ON a.document_id = b.document_id
ORDER BY a.count + b.count

---

对于那些想要这样做的人，这只适用于：

select wd.document_id, (wd.count + d.count) as tcount from word_document as wd
join words as w on w.id = wd.word_id
join
(select document_id, count from word_document 
join words on words.id = word_document.word_id
where words.word = "apple") d on d.document_id=wd.document_id
where w.word = "blue" order by tcount desc

---

您可以从内部查询创建临时表，并在该表上执行外部查询。可以递归地完成更多的单词。

马哈茂德的回答对我来说很有效，我不知道哪一个更好。但我认为他的更好，因为它只查询了一次word_文档！
