I am working on Spring MVC with MongoDB.
I have added criteria for some fields with orOperator, Each Fields has value in database, but List returning is Empty.
criteriaQuery.addCriteria(Criteria.where("First_Name").is(docName.trim())
.orOperator(Criteria.where("Middle_Name").is(docName.trim())
.orOperator(Criteria.where("Last_Name").is(docName.trim()))));
Query printing in console is
Query: { "First_Name" : "ESTHER" , "$or" : [ { "Middle_Name" : "ESTHER" , "$or" : [ { "Last_Name" : "ESTHER"}]}]}, Fields: null, Sort: null
I tried the Like query, but that also results the same
criteriaQuery.addCriteria(Criteria.where("First_Name").regex(docName)
.orOperator(Criteria.where("Middle_Name").regex(docName))
.orOperator(Criteria.where("Last_Name").regex(docName)));
Mongo Query
db.doctor_details.find({ "$or" : {"First_Name" : { "$regex" : "ESTHER"} }, "$or" : [ { "Middle_Name" : { "$regex" : "ESTHER"} , "$or" : [ { "Last_Name" : { "$regex" : "ESTHER"}}]}]})
Help me to get the result, I dont know where my code goes wrong. Help is appreciated!
Thanks
As far as I remember in order to use orOperator you should do:
Query query = new Query(new Criteria().orOperator(criteriaV1,criteriaV2));
it is based on this answer

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!

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' } ] },
{ $and : [ { '_id' : ObjectId("5c497...") }, { 'shared' : true } ] }
]})
I solved the problem with #Query
#Query("{\$or: [{\$and: [{'_id' : ?0}, {'owner' : ?1}]}, {\$and: [{'_id' : ?0}, {'shared' : true}]} ]}")
fun findIfAvailable(id: ObjectId, owner: String, shared: Boolean = true): Mono<MyObj>
But now, I wondered if it's possible to writing a method name for simplify the code ( and learn how use it ).
I tried without success findByIdAndOwnerOrShared, findByIdAndOwnerOrIdAndShared and so on
Thank you
For mongodb 3.2 following query successfully worked.
db.user_log.aggregate([{ "$match" : { "user_id" : "1" , "page_id" : "678761252281073"}} , { "$sort" : { "meta_data.access_times" : -1}} , { "$group" : { "_id" : { "first_name" : "$meta_data.user_data.first_name" , "last_name" : "$meta_data.user_data.last_name" , "profile_pic" : "$meta_data.user_data.profile_pic" , "user_id" : "$user_id" , "star_value" : "$star_value" , "access.times" : "$meta_data.access_times"}}}])
Java code -
Aggregation aggregation = newAggregation(
match(Criteria.where("user_id").is("123")),
sort(Sort.Direction.DESC, "meta_data.access_times"),
group(Fields.fields().and("first_name", "$meta_data.user_data.first_name").and("last_name", "$meta_data.user_data.last_name").and("profile_pic", "$meta_data.user_data.profile_pic").and("user_id", "$user_id").and("star_value", "$star_value").and("access.times", "$meta_data.access_times"))
);
AggregationResults<UsersMongoResult> groupResults = mongoTemplate.aggregate(aggregation, "user_log", UsersMongoResult.class);
but after upgrading to 3.4 it occurs following exception
org.springframework.dao.InvalidDataAccessApiUsageException: Command
execution failed: Error [FieldPath field names may not contain '.'.]
what is the reason behind this and how do I fix the issue
?
Issue is access.times, It is a bad practice to have . in your fields as it collides with nested elements.
I have a use case of elastic search to update a doc.
My doc is something like this-
{
"first_name" : "firstName",
"last_name" : "lastName",
"version" : 1234,
"user_roles" : {
"version" : 12345,
"id" : 1234,
"name" : "role1"},
},
"groups" : {
"version" : 123,
"list": [
{"id":123, "name" : "ashd"},
{"id":1234, "name" : "awshd"},
]
}
}
Now depepeding on some feed I will either will be updating the parent doc or will be updating the nested doc.
I am able to find how to update the basic attributes like firstName and lastName but unable to get how to update complex/nested ones
I did something like from REST client-
"script": {
"inline": "ctx._source.user_roles = { "id" : 5678, "name" :"hcsdl"}
}
but its giving me exception-
Actual use case-
I will actually be getting a Map in java.
This key can be simple key like "first_name" or can be complex key like "user_role" and "groups"
I want to update the document using update by query on version.
The code I wrote is something like-
for (String key : document.keySet()) {
String value = defaultObjectMapper.writeValueAsString(document.get(key));
scriptBuilder.append("ctx._source.");
scriptBuilder.append(key);
scriptBuilder.append('=');
scriptBuilder.append(value);
scriptBuilder.append(";");
}
where document is the Map
Now I might get the simple fields to update or complex object.
I tried giving keys like user_roles.id and user_roles.name and also tried giving complete user_roles but nothing is working.
Can someone helpout
Try this with groovy maps instead of verbatim JSON inside your script:
"script": {
"inline": "ctx._source.user_roles = [ 'id' : 5678, 'name' : 'hcsdl']}
}
