I'm new to Spring Data with MongoDB and would like to have an automagically generated query method inside my MongoRepository extension interface which requires filtering, sorting and limiting. The query looks like this: // 'created' is the field I need to sort against find({state:'ACTIVE'}).sort({created:-1}).limit(1) The repository interface looks like this: public interface JobRepository extends MongoRepository<Job, String> { @Query("{ state: 'ACTIVE', userId: ?0 }") List<Job> findActiveByUserId(String userId); // The next line is the problem, it wont work since // it's not in the format

How can I sort a MongoDB collection by a given field, case-insensitively? By default, I get A-Z before a-z. I'm using Java. Sammaye Update: As of now mongodb have case insensitive indexes: Users.find({}) .collation({locale: "en" }) .sort({name: 1}) .exec() .then(...) shell: db.getCollection('users') .find({}) .collation({'locale':'en'}) .sort({'firstName':1}) Update: This answer is out of date, 3.4 will have case insensitive indexes. Look to the JIRA for more information https://jira.mongodb.org/browse/SERVER-90 Unfortunately MongoDB does not yet have case insensitive indexes: https://jira

Given this document saved in MongoDB { _id : ..., some_key: { param1 : "val1", param2 : "val2", param3 : "val3" } } An object with new information on param2 and param3 from the outside world needs to be saved var new_info = { param2 : "val2_new", param3 : "val3_new" }; I want to merge / overlay the new fields over the existing state of the object so that param1 doesn't get removed Doing this db.collection.update( { _id:...} , { $set: { some_key : new_info } } Will lead to MongoDB is doing exactly as it was asked, and sets some_key to that value. replacing the old one. { _id : ..., some_key: {
