Mysql 拆下'；重复'；从全文查询

我正在扩展默认的WordPress全文搜索，并有一个SQL查询，如下所示

SELECT SQL_CALC_FOUND_ROWS DISTINCT wp_posts.*,
  MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE) AS p_score,
  MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE) AS pm_score
FROM wp_posts
  LEFT JOIN wp_postmeta ON wp_posts.ID = wp_postmeta.post_id
  LEFT JOIN wp_icl_translations ON wp_posts.ID = wp_icl_translations.element_id
  LEFT JOIN wp_icl_languages ON wp_icl_translations.language_code = wp_icl_languages.code AND wp_icl_languages.active = 1
WHERE 1=1
  AND IF(
    MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE) > MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE),
    MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE) > 0,
    MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE) > 0
  )
  AND wp_icl_translations.language_code = 'hr'
  AND wp_posts.post_status = 'publish'
ORDER BY p_score DESC LIMIT 0, 12

问题是，我在结果表中既有

p_分数

又有

pm_分数

，因此重复会像这样发生

ID  | ... | p_score  | pm_score
234 | ... | 9.234234 | 8.234323
234 | ... | 9.234234 | 0

虽然从技术上讲，它们不是重复的（不同的分数），但我仍然在搜索中看到重复的

是否可以进行查询，以便在获得

匹配的结果后，比较哪个分数（
p\u分数
或
pm\u分数
）更高，然后选择分数更高的分数来显示？我在
WHERE
子句中尝试了类似的方法，但显然，我做错了什么。
您应该能够使用MySQL函数

SELECT SQL_CALC_FOUND_ROWS DISTINCT wp_posts.*,
  GREATEST(
    MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE),
    MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE)
  ) as score
FROM wp_posts
  LEFT JOIN wp_postmeta ON wp_posts.ID = wp_postmeta.post_id
  LEFT JOIN wp_icl_translations ON wp_posts.ID = wp_icl_translations.element_id
  LEFT JOIN wp_icl_languages ON wp_icl_translations.language_code = wp_icl_languages.code AND wp_icl_languages.active = 1
WHERE 1=1
  AND IF(
    MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE) > MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE),
    MATCH (wp_posts.post_title, wp_posts.post_content) AGAINST ('"string" @4' IN BOOLEAN MODE) > 0,
    MATCH (wp_postmeta.meta_value) AGAINST ('"string" @4' IN BOOLEAN MODE) > 0
  )
  AND wp_icl_translations.language_code = 'hr'
  AND wp_posts.post_status = 'publish'
ORDER BY p_score DESC LIMIT 0, 12

这样，您就可以从这两个选项中选择最大的一个，并将它们作为
分数
进行计算

如果您想知道这是一个
p_分数
还是
pm_分数
，那么您可能需要不断获取这两个分数，并在代码级别处理重复项和比较。
这样可以消除重复项。我对最高分来自哪一部分并不感兴趣，只在乎分数：）谢谢！
