我有这个课程:
/**
* @ODM\Document
* @Indexes({
* @Index(keys={"status"="asc", "regDate"="desc", "expDate"="asc", "isFeatured"="asc"}),
* @Index(keys={"status"="asc", "visits.total"="asc", "visists.today"="asc"}),
* @Index(keys={"status"="asc", "price.value"="asc", "regDate"="asc"})
* })
*/
class Product {
/**
* @ODM\Date
*/
protected $regDate;
/**
* @ODM\Date
*/
protected $expire;
/**
* @ODM\EmbedOne(targetDocument="Price")
*/
protected $price;
/**
* @ODM\Boolean
*/
protected $isFeatured;
/**
* @ODM\EmbedMany(targetDocument="Visit")
*/
protected $visits;
}
/**
* @ODM\EmbeddedDocument
*/
class Price {
/**
* @ODM\Int
*/
protected $value;
/**
* @ODM\String
*/
protected $currency;
}
/**
* @ODM\EmbeddedDocument
*/
class Visit {
/**
* @ODM\Int
*/
protected $total;
/**
* @ODM\Int
*/
protected $today;
/**
* @ODM\EmbedMany(targetDocument="VisitPerDate")
*/
protected $perDate = array();
}
/**
* @ODM|EmbeddedDocument
*/
class VisitPerDate {
/**
* @ODM\Date
*/
protected $date;
/**
* @ODM\Int
*/
protected $visit;
}
我想在Product Document上应用多个复合索引.我想要添加到数据库的索引如下:
{ "status"=1, "regDate"=-1, "expDate"=1, "isFeatured"=1 }
{ "status"=1, "visits.total"=1, "visits.today"=1, "regDate"=1 }
{ "status"=1, "price.value"=1, "regDate"=1 }
我的索引注释是否正确?
似乎第一个索引必须正确,但我认为第二个和第三个索引是不正确的!
最佳答案 我认为ODM还不能应用索引.您可能需要在mongo.exe命令行中通过这样的命令应用索引:
use yourDbName
db.ensureIndexes()
