I have a Spring app thats connected to a mongo database, and am using the following code to get documents from a certain collection that are within a radius of a point on Earth:
"query" : {
"location" : {
"$geoWithin" : {
"$centerSphere" : [
[
37.33240731,
-122.03046898
],
0.0018924144710663706
]
}
}
}
Usually this works (for locations in england), however, for some reason these coordinates (in america) give this error:
'{ "ok" : 0.0, "errmsg" : "longitude/latitude is out of bounds, lng: 37.3323
lat: -122.031", "code" : 2 }
What could be causing this?
Faced the same problem while using spring data mongodb, the very silly mistake was the exchange of lat and long values.
Query query = new BasicQuery(
"{ location: { $geoWithin: { $centerSphere: [ [
-122.031,
37.3323
"+ rangeInMiles / 3963.2 +
" ] } }, visible : true, status : 'ACTIVE' }"
);

I have a CosmosDb - MongoDb collection that I'm using purely as a key/value store for arbitrary data where the _id is the key for my collection.
When I run the query below:
globaldb:PRIMARY> db.FieldData.find({_id : new BinData(3, "xIAPpVWVkEaspHxRbLjaRA==")}).explain(true)
I get this result:
{
"_t" : "ExplainResponse",
"ok" : 1,
"queryPlanner" : {
"plannerVersion" : 1,
"namespace" : "data.FieldData",
"indexFilterSet" : false,
"parsedQuery" : {
"$and" : [ ]
},
"winningPlan" : {
},
"rejectedPlans" : [ ]
},
"executionStats" : {
"executionSuccess" : true,
"nReturned" : 1,
"executionTimeMillis" : 106,
"totalKeysExamined" : 0,
"totalDocsExamined" : 3571,
"executionStages" : {
},
"allPlansExecution" : [ ]
},
"serverInfo" : #REMOVED#
}
Notice that the totalKeysExamined is 0 and the totalDocsExamined is 3571 and the query took over 106ms. If i run without .explain() it does find the document.
I would have expected this query to be lightning quick given that the _id field is automatically indexed as a unique primary key on the collection. As this collection grows in size, I only expect this problem to get worse.
I'm definitely not understanding something about the index and how it works here. Any help would be most appreciated.
Thanks!

Spring data Match and Filter Nested Array

Closed 3 years ago.
I'm looking to search into my collection and retreive only element who matched Criteria.
Here is my collection :
{
"_id" : "id",
"name" : "test",
"groupUsers" : [
{
"name" : "blabla",
"toys" : [
{
"createdAt" : ISODate("2019-10-30T12:59:41.409Z"),
},
{
"createdAt" : ISODate("2019-11-30T12:59:10.409Z"),
},
{
"createdAt" : ISODate("2019-12-30T12:59:12.409Z"),
}
],
"createdAt" : ISODate("2019-10-30T12:33:39.036Z")
},
{
"name" : "blabla2",
"toys" : [
{
"createdAt" : ISODate("2019-10-32T12:59:41.409Z"),
},
{
"createdAt" : ISODate("2019-11-30T12:59:56.409Z"),
},
{
"createdAt" : ISODate("2019-12-30T12:59:15.409Z"),
}
],
"createdAt" : ISODate("2019-10-32T12:33:39.036Z")
}
],
}
I want to retreive the whole collection but it depends when the user was added to the group for example, user blabla2 (in the example above) will only get the whole group but with only the two last toys of the first user in the response.
Anyway, I guess it's something really basic but I don't know why I can't figure it out.
What I'm Doing
I'm doing a first query to get the current user and get when he was added in the group (notice that the date gets converted into java Date Util here).
Aggregation groupAgg = newAggregation(match(Criteria.where("_id").is(groupId).and("groupUsers.userId").is(userId)));
GroupUser groupUser = mongoTemplate.aggregate(groupAgg, Group.class, GroupUser.class).getUniqueMappedResult();
In a second query, I want to get the whole document but only with the Criteria that I define before.
MatchOperation matchedGroup = match(new Criteria("_id").is(groupId));
MatchOperation matchedToys = match(
new Criteria("groupUsers.toys.createdAt").gte(groupUser.getCreatedAt()));
Aggregation aggregation = newAggregation(matchedGroup, matchedToys);
AggregationResults<Group> result = mongoTemplate.aggregate(aggregation, Group.class, Group.class);
Group group = result.getUniqueMappedResult();
This query doesn't work, and I'm looking to something like even if there is no match (for example, none toys has been created yet), it still return the group basic response and not null.
Maybe I need to unwind the nested array ?
Any help is appreciate. I'm using spring data.
Try this query
db.testers.aggregate([
{
$addFields:{
"groupUsers":{
$map:{
"input":"$groupUsers",
"as":"doc",
"in":{
$mergeObjects:[
"$$doc",
{
"toys":{
$filter:{
"input":"$$doc. toys",
"as":"sn",
"cond": {
"$and": [
{ "$gte": [ "$$sn.createdAt", ISODate('2015-06-17T10:03:46.000Z') ] },
]
}
}
}
}
]
}
}
}
}
}
]).pretty()
According to the documentation, I'm trying to get a working name for a method of a Spring MongoRepository that have to meet two different conditions. In plain words, the query sounds like: "look up for a determinate object by his id and it is one of mine or I want to share it"
The object:
{
"_id" : ObjectId("5c497..."),
"owner" : "myUserId",
"shared" : false,
}
The query:
db.getCollection('collection').find({$or : [
{ $and : [ { '_id' : ObjectId("5c497...") }, { 'owner' : 'myUserId' } ] },
{ $and : [ { '_id' : ObjectId("5c497...") }, { 'shared' : true } ] }
]})
I solved the problem with #Query
#Query("{\$or: [{\$and: [{'_id' : ?0}, {'owner' : ?1}]}, {\$and: [{'_id' : ?0}, {'shared' : true}]} ]}")
fun findIfAvailable(id: ObjectId, owner: String, shared: Boolean = true): Mono<MyObj>
But now, I wondered if it's possible to writing a method name for simplify the code ( and learn how use it ).
I tried without success findByIdAndOwnerOrShared, findByIdAndOwnerOrIdAndShared and so on
Thank you

After asking question to understand a bit more of the aggregation framework in MongoDB I finally found the way to do aggregation for my need (thanks to a StackExchange user)
So basically here is a document from my collection:
{
"_id" : ObjectId("s4dcsd5s4d6c54s6d"),
"items" : [
{
type : "TYPE_1",
text : "blablabla"
},
{
type : "TYPE_2",
text : "blablabla"
},
{
type : "TYPE_3",
text : "blablabla"
},
{
type : "TYPE_1",
text : "blablabla"
},
{
type : "TYPE_2",
text : "blablabla"
},
{
type : "TYPE_1",
text : "blablabla"
}
]
}
The idea was to be able to filter only some elements of my collections (avoiding Type 2 and 3). In fact I have more than 30 types and 6 are not allowed but for simplicity I made this example.
So the aggregation command in command line is this one:
db.history.aggregate([{
$match: {
_id: ObjectId("s4dcsd5s4d6c54s6d")
}
}, {
$unwind: '$items'
}, {
$match: {
'items.type': { '$nin': [ "TYPE_2" , "TYPE_3"] }
}
},
{ $limit: 10 }
]);
With this I am able to retrieve the 10 elements items of this document which do not match TYPE_2 and TYPE_3
However when I am using spring data there is no output. I looked a bit at the example to build mine but its still not working.
So I did:
Aggregation aggregation = newAggregation(
match(Criteria.where("id").is(myID)),
unwind("items"),
match(Criteria.where("items.type").nin(ignoreditemstype)),
limit(3),
skip(offsetLong)
);
AggregationResults<PersonnalHistory> results = mongAccess.getOperation().aggregate(query,
"items", PersonnalHistory.class);
PersonnalHistory is marked with annotation #Document(collection = "history") and id with the #id annotation
ignoreditemstype is a list containing TYPE_2 and TYPE_3
Here is what I have in the toString method of aggregation:
{
"aggregate" : "__collection__" ,
"pipeline" : [
{ "$match": { "id" : "s4dcsd5s4d6c54s6d"} },
{ "$unwind": "$items"},
{ "$match": { "items.type": { "$nin" : [ "TYPE_2" , "TYPE_3" ] } } },
{ "$limit" : 3},
{ "$skip" : 0 }
]
}
I tried a lot of stuff (to have at least an answer :) ) like removing id or the nin:
aggregation = newAggregation(
unwind("items"),
match(Criteria.where("items.type").nin(ignoreditemstype)),
limit(3),
skip(offsetLong)
);
aggregation = newAggregation(
match(Criteria.where("id").is(myid)),
unwind("items")
);
For information when I do a simple query like:
query.addCriteria(Criteria.where("id").is(myID));
My document is returned. However I have thousands of items. So I just want to have the 15 first (in fact the 15 first are the 15 last added)
Do you maybe see what I am doing wrong?
Yeah looks like you are passing simple String while it is expecting ObjectId
Aggregation aggregation = newAggregation(
match(Criteria.where("_id").is(new ObjectId(myID))),
unwind("items"),
match(Criteria.where("items.type").nin(ignoreditemstype)),
limit(3),
skip(offsetLong)
);
Now the question is why it works with simple query, my answer would be because spring-data driver is not that mature at least not with aggregation pipeline.
