我有這個類：MongoDB ODM索引：如何在一個自己擁有EmbeddedDocument的文檔中索引多個複合索引？
/**
* @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;
}
我想在產品上應用Document.The指標我想添加到數據庫中的多個複合索引有以下幾種：
{ "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 }
是我的索引標註是否正確？ 看來，第一個索引必須是正確的，但我認爲第二個和第三個索引是不正確的！
