How to optimise MongoDB search with indexing? - mongodb

Question

These documents are in my MongoDB collection:
{
"_id" : ObjectId("57f5e1b5c7739d9805edfe85"),
"date" : ISODate("2016-10-01T00:00:00.000Z"),
"query" : "test1",
"page" : "page1/runway/ready-to-wear/ss17/2016/10/christian-dior/",
"clicks" : 17.0,
"impressions" : 161.0,
"ctr" : 0.10559006211180125,
"position" : 8.503105590062113
}
{
"_id" : ObjectId("57f5e1b5c7739d9805edfe86"),
"date" : ISODate("2016-10-01T00:00:00.000Z"),
"query" : "test1",
"page" : "page2/runway/ready-to-wear/ss17/2016/10/christian-dior/",
"clicks" : 17.0,
"impressions" : 161.0,
"ctr" : 0.10559006211180125,
"position" : 8.503105590062113
}
{
"_id" : ObjectId("57f5e1b5c7739d9805edfe87"),
"date" : ISODate("2016-10-01T00:00:00.000Z"),
"query" : "test2",
"page" : "page3/runway/ready-to-wear/ss17/2016/10/christian-dior/",
"clicks" : 17.0,
"impressions" : 161.0,
"ctr" : 0.10559006211180125,
"position" : 8.503105590062113
}
I need to filter and get some documents like these:
{
"_id" : ObjectId("57f5e1b5c7739d9805edfe85"),
"date" : ISODate("2016-10-01T00:00:00.000Z"),
"query" : "test1",
"page" : "page1/runway/ready-to-wear/ss17/2016/10/christian-dior/",
"clicks" : 17.0,
"impressions" : 161.0,
"ctr" : 0.10559006211180125,
"position" : 8.503105590062113
}
{
"_id" : ObjectId("57f5e1b5c7739d9805edfe86"),
"date" : ISODate("2016-10-01T00:00:00.000Z"),
"query" : "test1",
"page" : "page2/runway/ready-to-wear/ss17/2016/10/christian-dior/",
"clicks" : 17.0,
"impressions" : 161.0,
"ctr" : 0.10559006211180125,
"position" : 8.503105590062113
}
I created an index using query field and ran db.query using aggregate() method like this:
{
"aggregate" : "Mycollection Name" ,
"pipeline" : [
{ "$match" : { "$text" : { "$search" : "\"test1\""}}},
{ "$match" : { "date" : { "$gte" : { "$date" : "2016-10- 01T00:00:00.000Z"} ,"$lte" : { "$date" : "2016-10-01T00:00:00.000Z"}}}},
{ "$group" : { "_id" : "$page" , "clicks" : { "$sum" : "$clicks"} , "impressions" : { "$sum" : "$impressions"} , "ctr" : { "$avg" : "$ctr"} , "position" : { "$avg" : "$position"}}} ,
{ "$sort" : { "clicks" : -1}}
]
}
This query is working but it is not return exactly search.
How can I optimize this query?
