  1. If sorting on multiple fields, sort order is evaluated from left to right. For example, in the form above, documents are first sorted by <field1>.Then documents with the same <field1> values are further sorted by <field2>.. Behavior¶ Sort Consistency¶. MongoDB does not store documents in a collection in a particular order
  2. sort: if multiple docs are found by the conditions, sets the sort order to choose which doc to update maxTimeMS : puts a time limit on the query - requires mongodb >= 2.6.0 runValidators : if true, runs update validators on this command
  3. The limit () function in MongoDB is used to specify the maximum number of results to be returned. Only one parameter is required for this function.to return the number of the desired result. Sometimes it is required to return a certain number of results after a certain number of documents. The skip () can do this job
  4. ing how Mongoose documents get serialized by JSON.stringify() 'strict': true by default, may be false, true, or 'throw'. Sets the default strict mode for schemas. 'selectPopulatedPaths': true by default. Set to false to opt out of Mongoose adding all fields that you populate() to your select()
  5. Using limit() with sort()¶ If using limit() with sort() , be sure to include at least one field in your sort that contains unique values, before passing results to limit() . Sorting on fields that contain duplicate values may return an inconsistent sort order for those duplicate fields over multiple executions, especially when the collection is actively receiving writes
  6. Mongoose 3.x is complaining about the [] parameter in your findOne calls as the array format is no longer supported for the parameter that selects the fields to include.. Try this instead to find the newest: Tweet.findOne({}, {}, { sort: { 'created_at' : -1 } }, function(err, post) { console.log( post ); }); Change the -1 to a 1 to find the oldest
  7. I want to sort a collection of Users by the name of their Group, alphabetically. I am currently doing this: UserModel.find({key, skip, limit}).populate({ path: group, select: nome }).sort({group.nome: asc}) But it is not sorting at all. Thank you for your help

GET /users?_sort=email:DESC,username:ASC # Limit. Limit the size of the returned results. # Example. Limit the result length to 30. GET /users?_limit=30.

Paging through your data is one of the most common operations with MongoDB. A typical scenario is the need to display your results in chunks in your UI. If you're batch processing your data, it's also important to get your paging strategy correct so your data processing can scale In Mongoose, the Model.find() function is the primary tool for querying the database. The first parameter to Model.find() is a filter object. MongoDB will search for all documents that match the filter.If you pass an empty filter, MongoDB will return all documents. In this tutorial, you'll see how to execute common queries in Mongoose by structuring the filter object using MongoDB query operators If we have an existing mongoose document and want to populate some of its paths, mongoose >= 3.6 supports the document#populate() method. Populating multiple existing documents. If we have one or many mongoose documents or even plain objects (like mapReduce output), we may populate them using the Model.populate() method available in mongoose.
