Getting SolrNet and Modeling the Data. Solr provides a REST-like API that you can easily use from any application. Even better, there’s a library called SolrNet (bit.ly/2XwkROA) that provides an abstraction over Solr, allowing you to easily work with strongly typed objects, with plenty of functionality to make search application development. There may be use cases where you want to integrate with Solr using the SolrNet library instead of going through Sitecore Content Search API. This post describes how to configure and work with Solr using SolrNet library with code snippets to perform different queries such as FilterQuery Parameter, Facet Parameters, Filter Query Parameters with Values, Facet Pivot Parameters, Grouping Parameters.

SolrNet is a .NET Open Source client for Apache Solr. This version of SolrNet is compatible with Solr 1.x to Solr 7.x. This package comes with a build in easy to use Dependency Injection for SolrNet.Core.

UPDATE 2/19/2009: by now most of this is obsolete, please check out more recent releases

Last month I've been working my a** off integrating Solr to our main site. The first step was to find out how to communicate with the Solr server. Naturally, I came to SolrSharp. But I found it to be really IoC-unfriendly: lots of inheritance, no interfaces, no unit-tests, so it would have been a real PITA to integrate it to Castle. So, instead of wrapping it, I built SolrNet.

Before explaining how it works, a disclaimer: I'm a complete newbie to Solr, Lucene and full-text searching in general. The code works on my machine and does what I need it to do for the task that I have at hand. This project is not, and might never be, feature complete like SolrSharp. Currently it doesn't support facets (UPDATE 8/20/08: I added facet support) or highlights, and maybe some other stuff. If you absolutely need those features right now, either use SolrSharp or write a patch for SolrNet. However, the next step in the integration is implementing faceted search, so I will definitely implement facets sooner or later.

Usage

First we have to map the Solr document to a class (Solr supports only one document type per instance at the moment). Let's use a subset of the default schema that comes with the Solr distribution:

It's just a POCO with a marker interface (ISolrDocument)^[1] and some attributes: SolrField maps the attribute to a Solr field and SolrUniqueKey (optional) maps an attribute to a Solr unique key field. Let's add a document (make sure you have a running Solr instance first):

Let's see if the document is there:

For more examples, see the tests.

DSL

Solrnet Cloud Example

Since DSLs are such a hot topic nowadays, I decided to give it a try to see what happened. I just defined the syntax I wanted in a test, then wrote the interfaces to comply to the syntax and chain the methods, then built the implementations for those interfaces. The result is pretty much self-explanatory:

Run() is the explicit kicker method^[1]. The DSL is defined in a separate DLL, in case you don't want/need it. There are some more examples in the tests.

I TDDd most of the project, so the code coverage is near 75%. I'll add the remaining tests if/when I have the time. Of course, as usual, patches/bugfixes are more than welcome :-)
