here is my query :

 db.books.aggregate([
 {$match:{'bookCategory.categoryCode' :  {$regex : 'Cooking/'}}},
  {$unwind:'$bookCategory'}, 


{ "$group": {
"_id": {
    "categoryCode": "$bookCategory.categoryCode",
    "book": "$bookName"
},
"revenue": { $sum:"$revenue" },
 "unitsSold": { $sum:"$unitsSold" }
}
 }]);

I am getting the documents related to categories 'Food Receipe/Bartending', 'Food Receipe/' alongwith 'Cooking/' categories.

Here is the sample output:

/* 1 */
{
"_id" : {
    "categoryCode" : "Cooking/",
    "book" : "Test6"
},
"revenue" : 10.0,
"unitsSold" : 1
}

/* 2 */ 
{
"_id" : {
    "categoryCode" : "Food Receipe/Bartending",
    "book" : "Test4"
},
"revenue" : 43.0,
"unitsSold" : 14
}

/* 3 */
 {
"_id" : {
    "categoryCode" : "Cooking/",
    "book" : "Test1"
},
"revenue" : 46.0,
"unitsSold" : 17
}

/* 4 */
{
"_id" : {
    "categoryCode" : "Food Receipe/Taste",
    "book" : "Test2"
},
"revenue" : 12.0,
"unitsSold" : 3
}

 /*And so on upto 48 documents*/

I am trying to match 'Cooking/' but its retrieving non matched documents. Please help in retrieving only the subdocuments matching 'Cooking/' and 'Cooking/Beverages', 'Cooking/Beverages/Bartending'.

Kris
