我正在为ElasticSearch阅读Reqexp Query但不知何故它对我不起作用。
我想找到任何包含" card"的产品。我的查询是这样的:
SELECT
`periode_class_members`.`id`,
`classes`.`id` AS `class`,
`periode_class_members`.`periode`,
`user`.`firstname` AS `firstname`,
`user`.`lastname` AS `lastname`,
`periode_class_members`.`status`,
min(`periode_class_subjects`.`id`) AS pcs
FROM `periode_class_subject_members`
LEFT JOIN `periode_class_members`
ON periode_class_subject_members.periode_class_member = periode_class_members.id
RIGHT JOIN `periode_class_subjects`
ON periode_class_subject_members.periode_class_subject = periode_class_subjects.id
JOIN `classes`
ON periode_class_members.class = classes.id
LEFT JOIN `user`
ON periode_class_members.user = user.id
where `classes`.`id` = 1
group by `periode_class_members`.`id`,
`classes`.`id` ,
`periode_class_members`.`periode`,
`user`.`firstname`,
`user`.`lastname` ,
`periode_class_members`.`status`;
我点击率为零。知道我在这里缺少什么吗?
答案 0 :(得分:0)
您在正则表达式中遗漏了.
。
这应该有效:
{
"query": {
"regexp":{
"product": ".*card.*"
}
}
}
