Php MySQL全文搜索-搜索精确匹配的单词&；通配符，但先获得精确匹配，然后再进行其他匹配

我使用布尔全文搜索从数据库列中搜索单词。 我希望获得与我的记录完全匹配的记录&还包括通配符搜索。我得到了正确的结果，但我想先通过精确匹配来设置结果的顺序。有什么可能的方法来实现这一点吗

我还想对每个单词进行搜索&通过相关性获取记录

我尝试过使用下面的查询，但它不起作用，因为它为记录提供了错误的排名

    SELECT
      id,
      search_tags,
      MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," ","* ")  IN BOOLEAN MODE) AS relevance_rank
    FROM
      images
    WHERE
      MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," ","* ")  IN BOOLEAN MODE)
    ORDER BY relevance_rank DESC;

我希望查询的输出是

   id  search_tag             relevance_rank
   11  car,cards,food,code    2.1669161319732666
   12  car,water,sky          2.1669161319732665
   13  carrier,food,drink     2.1669161319732664

，但实际输出如下

   id  search_tag             relevance_rank1
   11  carrier,food,drink     2.1669161319732666
   12  car,cards,food,code    2.1669161319732666
   13  car,water,sky          2.1669161319732666

使用联合时应能正常工作：

SELECT
  id,
  search_tags,
  MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," "," ")  IN BOOLEAN MODE) AS relevance_rank,
1 as prio -- sort by priority first
FROM
  images
WHERE
  MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," "," ")  IN BOOLEAN MODE)
ORDER BY relevance_rank DESC 
UNION SELECT
  id,
  search_tags,
  MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," ","* ")  IN BOOLEAN MODE) AS relevance_rank,
 2 as prio -- sort by priority first
FROM
  images
WHERE
  MATCH(search_tags) AGAINST(REPLACE(concat("'car'"," ")," ","* ")  IN BOOLEAN MODE)
ORDER BY prio, relevance_rank DESC;

此查询将记录的整个单词排名较高，但

car、cards

的排名与

car

的排名相同，因此它仍然不是最优的

SELECT id, search_tags, 
    MATCH(search_tags) AGAINST('car *') + 
    MATCH(search_tags) AGAINST('car') AS relevance_rank
FROM images
WHERE MATCH(search_tags) AGAINST('car *') 
OR MATCH(search_tags) AGAINST('car')
ORDER BY 3 DESC

+----+---------------------+----------------+------------+ |id |搜索|标记|相关性|排名|出现次数| +----+---------------------+----------------+------------+ |12 |汽车、卡片、食品、代码| 0.1677478002 | 2| |13 |汽车、水、天空| 0.1677478002 | 1| |11 |载体、食品、饮料| 0.0093915509 | 1| +----+---------------------+----------------+------------+

我认为你应该使用laravel Scout:@DharmeshRakholia-但我已经使用了全文搜索，laravel Scout使用了相同的搜索。我没有使用MVC结构，所以不可能继续使用Laravel Scout。你还有别的办法吗？可能是@JorisJ1的复制品-我的问题不仅是为了秩序，而且我还有相同等级的混乱。你知道为什么它会有相同的排名吗？对不起，我删除了重复的旗帜。不，我还没有答案，但今天晚些时候我会再看一遍。 +----+---------------------+----------------+ | id | search_tags | relevance_rank | +----+---------------------+----------------+ | 12 | car,cards,food,code | 0.1677478002 | | 13 | car,water,sky | 0.1677478002 | | 11 | carrier,food,drink | 0.0093915509 | +----+---------------------+----------------+

SELECT id, search_tags, 
    MATCH(search_tags) AGAINST('car *') + 
    MATCH(search_tags) AGAINST('car') AS relevance_rank,
    LENGTH(search_tags) - 
    LENGTH(REPLACE(search_tags, 'car', space(LENGTH('car')) -1 )) AS occurences
