I want to restrict the search index in Sitecore 7 to only scan one node of the content tree.
Currently the structure looks like this:
The index is indexing both BaseNode & $Company Node, but I only want it to index $Company Node.
I've updated the default /sitecore/content path in Sitecore.ContentSearch.config, SitecoreContentSearch.Lucene.DefaultIndexConfiguration.config, Sitecore.ContentSearch.Lucene.Index.Master, and Sitecore.ContentSearch.LuceneIndex.Web.config. When I updated the <root> element to point to /sitecore/content/$CompanyNode, I get the following exception when I try to rebuild the indexes.
Any ideas what I need to do to restrict Lucene to just index some items, and not everything?

I believe you are attempting to modify the Master Lucene Index file. I believe that would break a lot of things in the end and I would recommend that you create a new Lucene Index file.
If you were to create a new Index: Place this index in your App_Config / Include Folder
Sitecore.ContentSearch.Lucene.Index.Alexander.config
In that config you set the crawler to search for your node.
<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">

<contentSearch>
<configuration type="Sitecore.ContentSearch.LuceneProvider.LuceneSearchConfiguration, Sitecore.ContentSearch.LuceneProvider">

</crawler>
</locations>
</index>
</indexes>
</configuration>
</contentSearch>
</sitecore>
</configuration>
This above index will index everything under that node. In C# you can easily call this with.
ContentSearchManager.GetIndex("alexander_search_index").Rebuild();
using (var searchContext = ContentSearchManager.GetIndex("alexander_search_index").CreateSearchContext())
{
var result = searchContext.GetQueryable<SearchResultItem>()
.Where(//Put Query Here);
//do ForEach if you return multiple and so on.
if (result != null)
Context.Item = result.GetItem();
}
You can also Rebuild your indexes and verify that they are working by going into Sitecore -> Control Panel -> Indexing -> Indexing Manager. After doing that you should see the Index.
Another Edit: You could also just perform your C# Search underneath that item in the content tree and use only the web database.
Item bucketItem = //Code to get $Company Node as a Sitecore Item
//Probably Sitecore.Context.Database.GetItem("Guid for $Company Node")
using (var searchContext = ContentSearchManager.GetIndex(bucketItem as IIndexable).CreateSearchContext())
{
try
{
var result = searchContext.GetQueryable<SearchResultItem>().Where(x => x.Name == itemName).FirstOrDefault();
if (result != null)
Context.Item = result.GetItem();
}
catch (Exception)
{
//Do something
}
}
