在开发模版的过程中，内容页比较多的会用到调用一些相关文章的做法，以下几种方法可以试试。
标题包含关键字
①、比较粗糙的匹配，可能不太精确：title like '%$navinfor[keyboard]%'
②、精确的匹配，比较消耗资源：title regexp '(^|,)$navinfor[keyboard]($|,)'
关键字相同
①、比较粗糙的匹配，可能不太精确：keyboard like '%$navinfor[keyboard]%'
②、精确的匹配，比较消耗资源：keyboard regexp '(^|,)$navinfor[keyboard]($|,)'
格式1：
①、模糊匹配
[e:loop={"select * from phome_ecms_news where title like '%$navinfor[keyboard]%' or keyboard like '%$navinfor[keyboard]%' order by id desc limit 10",0,24,0}]
[/e:loop]
②、精确的匹配
[e:loop={"select * from phome_ecms_news where title regexp '(^|,)$navinfor[keyboard]($|,)' or keyboard regexp '(^|,)$navinfor[keyboard]($|,)' order by id desc limit 10",0,24,0}]
[/e:loop]
格式2：
①、模糊匹配
[e:loop={'news',10,3,0,"keyboard like '%$navinfor[keyboard]%' or title like '%$navinfor[keyboard]%'",''}]
·
[/e:loop]
或
[e:loop={0,10,3,0,"keyboard like '%$navinfor[keyboard]%' or title like '%$navinfor[keyboard]%'",''}]
[/e:loop]
注意：在没有相关文章时，会调用最新的文章来替代空缺的位置
