问题 I have close to 3 million documents that are being stored in a RavenDb embedded instance. Everyone of the fields will be subjected to some type of filter/query/sorting, but in particular I wanted to do some type of intelligent textual search of the info and info2 columns. How might I go about constructing the RavenDb Indexes? My first pass at the info2 column looks like this. store.DatabaseCommands.PutIndex("ProdcustByInfo2", new IndexDefinitionBuilder<Product> { Map = products => from

问题 I've seen a lot of different ways of configuring Ninject with ASP.NET MVC, but the implementation seems to change slightly with each release of the MVC framework. I'm trying to inject a RavenDB session into my repository. Here is what I have that's almost working. public class MvcApplication : NinjectHttpApplication { ... protected override void OnApplicationStarted() { base.OnApplicationStarted(); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters);

问题 I'm using such a query: var query = "*" + QueryParser.Escape(input) + "*"; session.Query<User, UsersByEmailAndName>().Where(x => x.Email.In(query) || x.DisplayName.In(query)); With the support of a simple index: public UsersByEmailAndName() { Map = users => from user in users select new { user.Email, user.DisplayName, }; } Here I've read that: "By default, RavenDB uses a custom analyzer called LowerCaseKeywordAnalyzer for all content. (...) The default values for each field are FieldStorage

问题 My application includes a few queries which return large result sets (although I've capped it with a Take(300) lambda. During peak usage times, I've seen Raven.Server.exe consume an unusually large amount of RAM. In fact, during these times, Raven.Server.exe can exhaust my server's available RAM. How can I avoid this situation? After a few Google searches, I can see that other people have encountered this error before me. But RavenDB has evolved during the past few years and there are many

问题 I have some code that is searching a RavenDB database with the following index: public class Products_Search : AbstractIndexCreationTask<Product, Products_Search.Result> { public class Result { public string Query { get; set; } } public Products_Search() { Map = products => from product in products select new { Query = new { Categories = product.Categories.Boost(5), Brands = product.Brands.Boost(8), product.Description, Name = product.Name.Boost(10), product.SKU }, product.Price }; Index(x =>

问题 Is there a way to have Raven order the results of a query by the Id field as if it was in integer. So "cars/2" would come before "cars/11" if I did this query: var cars = session.Query<Car>().OrderBy(c => c.ID); 回答1: You shouldn't rely on the id of the document to be sortable in any way. Add a CreatedAt property or something similar and use that 来源： https://stackoverflow.com/questions/6144898/order-by-id-in-ravendb

问题 This is a continuation of the project outlined in this question. I have the following model: class Product { public string Id { get; set; } public string[] Specs { get; set; } public int CategoryId { get; set; } } The "Specs" array stores product specification name value pairs joined by a special character. For example if a product is colored blue the spec string would be "Color~Blue". Representing specs in this way allows querying for products having multiple spec values specified by a query

问题 I am using NServiceBus v4.3, MVC4, RavenDB 2.5 and StructureMap 2.6.4 in our solution. I am having a similar issue under StructureMap to that described in this question's responses where I require different lifecycles for the MVC Controller and NServiceBus Handler use of RavenDB's IDocumentSession in my Web project. Specifically in my case what happens is that if I use the HybridHttpOrThreadLocalScoped (as the above answer suggests for Windsor) lifecycle the sessions are not properly disposed

问题 I have a ravendb class like such: public class Student { public string Id { get; set; } public string TopLevelProperty { get; set; } public Dictionary&ltstring, string&gt Attributes { get; set; } public Dictionary&ltstring,List&ltDictionary&ltstring, string&gt&gt&gt CategoryAttributes { get; set; } } and a document like so: The following linq will not work due to a selectmany: test = (from student in session.Query() from eduhistory in student.CategoryAttributes["EducationHistory"] where
