mongodb-.net-driver

I'm not so good in Mongodb. That's my first project using this. I'm working on some sort of shop website. We're using C# and newest C# driver for mongodb. I need an idea how to implement my algorithm to filter products based on user's input. Here's how my algorithm works/should work. User type something like "Blue adidas men spiderman cotton t-shirt" I split whole phrase into single words so I have "blue", "adidas", "men", "spiderman", "cotton", "t-shirt" I check each word against retailer, color, category names in my db. So here's how it goes. "Blue" - oh, it's a color filter let's filter

I have to store a tiff(tag image file format) or pdf scanned file in mongodb that should be Text search able . like if we want to search "on base of text" it should be able to search . I am going to use .net mvc or java with mongodb . so how can i store this pdf file and then can retrieve from database . any suggestion will be appreciated . thanks shA.t You can store files by using MongoDb GridFs as described in this question and extract texts from a PDF file by using some features those described in this question . ;). HTH I think that you should save the files on file system of the server

I have many immutable value type classes, for example EmailAddress , which ensure any non null instance is valid. I would like to control the serialization of these types of objects to be just the standard string representation ( "123@abc.com" ) when persisted using MongoDB C# Driver. I have tried implementing the IBsonSerilizer however it will only allow for objects or arrays at the root level. I was able to implement proper Json Serilization with Json.NET, is there a different approach I should be taking? I assume you mean an EmailAddress class something like this: [BsonSerializer(typeof

In the older .Net API version : MongoClient client = new MongoClient(); var server = client.GetServer(); var db = server.GetDatabase("foo"); var collection = db.GetCollection<BsonDocument>("bar"); var document = new BsonDocument { { "_id", 1 }, { "x", 2 } }; collection.Save(document); It worked. When i use new .Net Driver 2.0 : var client = new MongoClient("mongodb://localhost:27017"); var database = client.GetDatabase("foo"); var collection = database.GetCollection<BsonDocument>("bar"); var document = new BsonDocument { { "_id", 1 }, { "x", 2 } }; await collection.InsertOneAsync(document);

I'd like to define in class declaration which items are index, something like: public class MyClass { public int SomeNum { get; set; } [THISISANINDEX] public string SomeProperty { get; set; } } so to have the same effect as ensureIndex("SomeProperty") Is this possible? I think this is a nice idea, but you have to do this yourself, there's no built-in support for it. If you have an access layer you can do it in there. You'd need an attribute class, something like this; public enum IndexConstraints { Normal = 0x00000001, // Ascending, non-indexed Descending = 0x00000010, Unique = 0x00000100,

I have been trying to get started but run into the same rock time after time trying to create and query MongoDB with C# official driver. The problem is how to create data with geo information. I am just not finding the answer. Code: MongoUrl url = new MongoUrl("mongodb://xxx.xx.x.xx/mydb"); MongoServer server = MongoServer.Create(url); MongoDatabase database = server.GetDatabase("mydb"); <-- this works fine BsonDocument[] batch = { new BsonDocument { { "name", "Bran" }, { "loc", "10, 10" } }, new BsonDocument { { "name", "Ayla" }, { "loc", "0, 0" } } }; places.InsertBatch(batch); <-- that part

Say I have this expression: int setsize = 20; Expression<Func<Foo, bool>> predicate = x => x.Seed % setsize == 1 || x.Seed % setsize == 4; This basically 'partitions' a set of elements into 20 partitions and retrieves from each set each first and fourth element. This expression is passed to MongoDB which it's driver is perfectly capable of translating into a MongoDB "query". The predicate can, however, also be used on a list of objects (LINQ2Objects) etc. I want this expression to be reusable ( DRY ). However, I want to be able to pass in an IEnumerable<int> to specify which items to retrieve
