This folder configures the various Content Sources that are used by Search Boost to get relevant content. 
A content source is basically a plugin that reads content from a source (such as database, files, etc) and makes it
available for Search Boost to index.

Normally you don't need to change the configuration in this folder unless you want to add your own plugins to gather content from 
new sources. In this case, create a new Json file similar to .defaults.json.config in terms of structure.

To implement a custom source plugin, reference  DnnSharp.SearchBoost.Core.dll in your project and
implement DnnSharp.SearchBoost.Core.ContentSource.IContentSource interface.

Then, create a new Json file in this folder and add your type like in the example below.

[
    {
        "Id": "SomeId",
        "Title": "My Content Source",
        "TypeStr": "Fully.Qualified.TypeName, MyAssembly"
    }
]
