I need to find collections based nested on values.But my collection having dynamic values . See below code. In which image name keys are dynamic ( _DSC9691.jpg , _DSC9514.JPG ) and " key1 " is dynamic items. Now I need to find collection based on component, material, Subtype
{
"_id" : ObjectId("5ce2df8498f10b276cb466c4"),
"num" : "1",
"lat" : "39.941436099965",
"lon" : "-86.0691700063581",
"images" : {
"_DSC9691.jpg" : {
"key1" : {
"component" : "Sleeve",
"condition" : "",
"sub_type" : {
"Auto Sleeve" : true
},
"material" : "",
"misc" : ""
}
}
}}
{
"_id" : ObjectId("5ce2df8498f10b276cb466c7"),
"num" : "4",
"lat" : "39.9413828961847",
"lon" : "-86.0715084495015",
"images" : {
"_DSC9554.JPG" : {
},
"_DSC9514.JPG" : {
},
"_DSC9622.JPG" : {
}
}}
#Nagendran you won't be able to perform those operations because the nested document that you want to watch isn't named properly. I suggest you to rename that field using a common name and try to use the code bellow. Also remember to not use blank spaces on field names like "Auto Sleeve".
Object:
{
"_id" : ObjectId("5ce2df8498f10b276cb466c7"),
"num" : "4",
"lat" : "39.9413828961847",
"lon" : "-86.0715084495015",
"images" : [
{
"name" : "some name",
"key":
{
"component" : "Sleeve",
"condition" : "",
"sub_type" : {
"Auto_Sleeve" : true
},
"material" : "",
"misc" : ""
},
},
{
"name" : "some name 2",
"key":
{
"component" : "Sleeve 2",
"condition" : "",
"sub_type" : {
"Auto_Sleeve" : true
},
"material" : "",
"misc" : ""
},
},
]
}
Query:
db.collection.find({
"images.key.sub_type.Auto_Sleeve": true
})
If you want you can use aggregation framework to filter inside the "images" nested document.
To get a litle bit more information you can access:

I am trying to query for Mongo documents based on 1 many key value pairs over a large collection of documents.
I am storing the values in an array called descriptors. I cannot figure out to write the query to consistently return results.
Basically I am trying to write the following SQL query in Mongo
select * from descriptors where
(id=123 and value="Latest based on new infor")
or
(id=3221 and value="Latest new info")
I have tried the following:
db.collection.find({$or: [
{ descriptors:
{
'$elemMatch':
{
id: 123,
value: 'Latest based on new infor',
}
}
},
{ descriptors:
{
'$elemMatch':
{
id: 3221,
value: 'Latest new info',
}
}
}
]
}
Here are sample documents.
{
"_id" : ObjectId("569d62673b020a47f0401325"),
"descriptors" : [
{
"id" : 123,
"name" : "Version",
"value" : "Latest based on new infor",
"parent" : null
},
{
"id" : 345,
"name" : "Eligibility Criteria",
"value" : "Really qualified ",
"parent" : null
}
],
}
{
"_id" : ObjectId("569dac2e4e6247c01bbac47f"),
"descriptors" : [
{
"id" : 3221,
"name" : "Version",
"value" : "Latest new info",
"parent" : null
},
{
"id" : 345,
"name" : "Eligibility Criteria",
"value" : "Different Value",
"parent" : null
}
],
}
{
"_id" : ObjectId("56bce4df7aae8369d8fc705d"),
"descriptors" : [
{
"id" : 3221,
"name" : "Version",
"value" : "Latest based on new infor",
"parent" : null
},
{
"id" : 345.0,
"name" : "Eligibility Criteria",
"value" : "Really qualified",
"parent" : null
}
],
}
Any help would be appreciated,

I have a list of documents like this.
[
{
"name" : "test",
"data" : [
{ "code" : "name", "value" : "Diego" },
{ "code" : "nick", "value" : "Darko" },
{ "code" : "special", "value" : true }
]
},
{
"name" : "another",
"data" : [
{ "code" : "name", "value" : "Antonio" },
{ "code" : "nick", "value" : "Tony" }
]
}
]
now I need to find all the documents that:
a) don't contain a "data" item with code "special"
OR
b) contains a "data" item with code "special" and value false
It's like I needed the opposite of $elemMatch or I'm missing something?
I'm assuming that you're inserting each document in your list of documents as a separate member of a collection test.
For a,
db.test.find({ "data.code" : { "$ne" : "special" } })
For b.,
db.test.find({ "data" : { "$elemMatch" : { "code" : "special", "value" : false } } })
Combining the two with $or,
db.test.find({ "$or" : [
{ "data.code" : { "$ne" : "special" } },
{ "data" : { "$elemMatch" : { "code" : "special", "value" : false } } }
] })
Hope this $nin will solve your issues.
I insertd your docs into "so" collection
db.so.find({}).pretty();
{
"_id" : ObjectId("5489cd4f4cb16307b808d4b2"),
"name" : "test",
"data" : [
{ "code" : "name",
"value" : "Diego"
},
{ "code" : "nick",
"value" : "Darko"
},
{ "code" : "special",
"value" : true
}
]
}
{
"_id" : ObjectId("5489cd674cb16307b808d4b3"),
"name" : "another",
"data" : [
{"code" : "name",
"value" : "Antonio"
},
{ "code" : "nick",
"value" : "Tony"
}
]
}
don't contain a "data" item with code "special"
> db.so.find({"data.code":{$nin:["special"]}}).pretty();
{
"_id" : ObjectId("5489cd674cb16307b808d4b3"),
"name" : "another",
"data" : [
{ "code" : "name",
"value" : "Antonio"
},
{ "code" : "nick",
"value" : "Tony"
}
]
}
contains a "data" item with code "special" and value false
db.so.find({$and:[{"data.code":"special"},{"data.value":false}]}).pretty();
I have a mongodb with a table named Patient. When I display the content with MongoVUE I see my Patients in this format:
/* 0 */
{
"_id" : ObjectId("547c4aa9dbe9665042dddf76"),
"Patient" : {
"Maidenname" : { },
"Phone" : {
"Type" : { },
"Number" : { }
},
"Citizenship" : { },
"SSN" : 1234567,
"Profession" : { },
"systemUID" : { },
"lid" : 111,
"system" : "abc",
"Address" : {
"Street" : { },
"State" : { },
"Zip" : { },
"Country" : { },
"City" : { }
},
"Lastname" : "asdf",
"Firstname" : "Test",
"Birthdate" : 19000101,
"Identifier" : {
"id" : 123,
"system" : "abc",
"UID" : { }
}
}
}
I would like to make a find on the field Firstname with value Test, this is my query:
db.Patient.find({Firstname:"Test"})
But it returns 0 rows.
I also tried this one:
db.Patient.find({Patient : {Firstname:"Test"}})
Also 0 rows returned.
When I do a find like this:
db.Patient.find()
I get all data. (also the one with "Firstname" : "Test")
Can anyone help me with that find query?
Should try this it work well
db.patiens.find({"Patient.Firstname":"Test"})
Since Firstname is in Patient object, it is its property you need to select is as
db.Patient.find({"Patient.Firstname":"Test"})
I need a way to find inside nested array documents.
I want to find value matching inside street_1.
this is my query:
db.phonebook.find({'address.home.street_1' : 'street 1 result'});
and my document:
{
"_id" : ObjectId("53788c0c74d3ead0098b4568"),
"first_name" : "jarod",
"last_name" : "petters",
"company" : "nostromos",
"phone_numbers" : [
{
"cell" : "0752203337"
},
{
"home" : "0850819201"
},
{
"home" : "0499955550"
}
],
"website" : "http://www.mywebsite.com",
"email" : [
{
"home" : "email.first.com"
},
{
"office" : "email.second.com"
}
],
"address" : [
{
"home" : {
"stree_1" : "street 1 result",
"stree_2" : "",
"postal_code" : "66502",
"city" : "my littre city",
"country" : "usa"
}
}
],
"nationality" : "mars",
"date_of_birth" : "1978-01-01"
}
Your query is the good one. But your document is not good, you have done a mistake in your document, you write stree_1 instead of street_1. If your document is right, change your query to :
db.phonebook.find({'address.home.stree_1' : 'street 1 result'});
I would like to only return my embedded documents titled 'Listings', based on the text search query. Where may I be going wrong? Creation of the index?
Here is my index:
db.Collection.ensureIndex({"Listings.Title": "text", "Listings.Description" : "text"}, {name: "Search"})
This returns the whole object, only want listings
db.AspNetUsers.runCommand("text", { search: "lawn" })
this returns just listings, but all the listings are included. Not the listings based on the search criteria e.g. 'lawn'
db.AspNetUsers.runCommand("text", { search: "lawn", project: {Listings:1}})
here is my object
{
"_id" : ,
"UserName" : "",
"PasswordHash" : "",
"SecurityStamp" : "",
"Roles" : [],
"Claims" : [],
"Logins" : [],
"ProfileData" : {

"FirstName" : "",

"MiddleName" : "",
"Address" : "",
"Address1" : ,
"City" : "",
"State" : "",
"PostalCode" : "",
"CellPhone" : "",
"HomePhone" : "",
"Location" : {
"type" : "Point",
"coordinates" : [, ]
}
},
"Email" : "",
"ConfirmationToken" : "Confirmed",
"IsConfirmed" : true,
"Listings" : [{
"_id" : ObjectId("5331ac28a5eabf2854085df5"),
"UserId" : ObjectId("5329b43fa5eabf0548490c27"),
"Title" : "Lawn Chairs",

}
}, {

"Category" : {
"_id" : ObjectId("53273cd57dd6c71e1859ab76"),

}
}]
}
You can get just the fields you want using a project parameter. For getting just the Listings element, you could try:
db.AspNetUsers.runCommand("text", {search:"lawn", project:{_id:0, Listings:1}})
EDIT:
The text command will return all documents that contain the search term. You'll get the entire document. If you further want to filter an array inside of the document, you can use the $elemMatch projection operator, in combination with $regex. For example:
db.AspNetUsers.runCommand("text", {
search: "lawn",
project: {_id:0, Listings:{$elemMatch:{ "Title": /lawn/i }}}
})
