Hi Mari,

I think Henrik may be able to help you get Dictionary2Find to work with the .NET 3.5 version. However, you should upgrade to the latest of that version (1.0.0.278 at this time).

Given that you're running build 278 you could also try to have a property of type Dictionary<string, IndexValue>. IndexValue is a special little class that can hold either a string, integer, double or datetime, which based on what you write probably would work for your needs.If you try that approach I'd love to hear how it goes.

Also, IndexValue is implicitly convertible from the above mentioned types, meaning that if you have a property named A of type Dictionary<string, IndexValue> you can do:

obj.A["a"] = 1;

obj.A["b"] = DateTime.Now;

Tried using version 1.0.0.278 and the IndexValue class, but it fails when trying to retrieve results, see error details below.
I`ve tried indexing using both 

Facets = new Dictionary<string, IndexValue> { { "carbon", "no" }, { "gears", "Shimano 105" } }

    
and

Facets = new Dictionary<string, IndexValue> { { "carbon", new IndexValue("no") }, { "gears", new IndexValue("Shimano 105") } }

Unable to find a constructor to use for type EPiServer.Find.IndexValue. A class should either have a default constructor, one constructor with arguments or a constructor marked with the JsonConstructor attribute.

Are you getting that when results are retrieved? If I recall correctly you should be able to filter by values in a dictionary with IndexValue as well as project from them. However I don't think the class was designed for actually retrieving. Not that it was explictly design not to be retrievable, but it was designed for extensibility in Unified Search.

Are you retrieving the indexed objects directly without any projection? Would adding a projection work for you?

Did some more quick testing (see results below) - will investigate further

// works for retrieving all items
            var res1 = client.Search<ProductIndexedEntry>().
                Select(x => new ProductIndexedEntry
                {
                    Name = x.Name,
                    Model = x.Model
                }).GetResult();

            // not working - throws error specified in previous post
            var res2 = client.Search<ProductIndexedEntry>().GetResult();

            // try to filter based on Dictionary key, not working - no results
            var res3 = client.Search<ProductIndexedEntry>().Filter(
                x => x.Facets.MatchContained(a => a.Key, "carbon")
                    ).GetResult();

            // not building: "Cannot convert lambda expression to type 'EPiServer.Find.Api.Querying.Filter' because it is not a delegate type
            var res4 = client.Search<ProductIndexedEntry>().Filter(
                x => x.Facets.MatchContained(a => a.Value, new IndexValue("yes"))
                    ).GetResult();

I'm a bit unsure how this works in the .NET 3.5 version but in the .NET 4/CMS 7 version you should be able to do this:

Filter(x => x.Facets["carbon"].Match("yes"))

If I go back to Dictionary<string,string> querying by value works:

Filter(x => x.Facets["carbon"].Match("yes")).

I'm not able to query by key (retrieving all items that has Facets key = "someKey"), but I guess I don't need that.

Great!

Filter(x => x.Facets["carbon"].Exists()) should give you by key I think.

Hi Mari,

Dictionary2Find work with the latest version of Find for CMS 6R2 (1.0.0.278) and now also supports filtering on keys or values.
