Can't query solr

When querying with solr-express i'm always running in a Aggregate exception. The aggregate exception itself contains the following message:

Running this query with postman works fine the query is build up like this:

IEnumerable<SolrDocument> docs;
this.documentCollection.Select().Execute().Document(out docs);

What am i doing wrong? Everything is correctly initialized and updating (indexing) files works..

Running with these nuget packages:

"SolrExpress.Core": "4.2.1",
"SolrExpress.Solr5": "4.2.1"

Using Solr: 6.4.1 And using dotnet core:

$ dotnet --info
.NET Command Line Tools (1.0.0-preview2-1-003177)

Product Information:
 Version:            1.0.0-preview2-1-003177
 Commit SHA-1 hash:  a2df9c2576

Runtime Environment:
 OS Name:     Windows
 OS Version:  10.0.14393
 OS Platform: Windows
 RID:         win10-x64

I've also downgraded from Solr 6.4 to 5.5.0 and still get the notice: The remote server returned an error: (501) Method GET-X is not defined in RFC 2068 and is not supported by the Servlet API

What is this mysterious GET-X method? i've never heard of it while reading the RFC i saw it's an extension method? (please explain) RFC 2068

I've added the following question at stackoverflow

FieldList in solr5

How can I project data in solr5?

I see there is FieldList parameter in solr4 that adds fl to the query but I don't see it in solr5

Is it missing or is there another way?

Better way to add default parameters to search

What? Drop class SystemParameter and add default parameters in SolrSearch class, Execute method.

Why? Avoid errors like (#174)

What it´s necessary? Create below parameters:

  • [x] EchoParams
  • [x] WriteType (generated wt)
  • [x] Indent
  • [x] Query Parser (generated defType)
  • [x] Standard query (generated q.alt)
  • [x] Default field (generated df)

Support for .NET Core 1.0.1 (1.1) and higher

@diegobrum:

Problem:

  • In my solution, I've a ASP.NET Core 1.0.1 application (targeting full .Net 4.6.2).
  • In the same solution I've a class library project (.NET 4.6.2), this class library has my search service implementation.
  • To this class library project I've added the SolrExpress5 package.
  • To the web app references the class library project.
  • When I run the application, it fails with the System.IO.FileLoadexception for Microsoft.Extensions.DependencyInjection.Abstractions 1.0.1. (and SolrExpress uses 1.0.0)

Work around:

  • I upgrade the Microsoft.Extensions.DependencyInjection.Abstractions, Microsoft.Extensions.DependencyInjection packages in my Class library project to 1.0.1
  • Add a runtime binding redirect in the app.config for the Web.app to these to assemblies, it works fine.

Fix (?): Are there plans to support .NET Core 1.0.1 (1.1) and higher or you should consider it soon.

Thanks

Under load solr-express hangs the kestrel

Hi,

We released site to production and we have hangs most probably caused by solr-express. I am investigating and I hope I will have more info soon.

Does solr express have any configurable timeout option?
