Hi,

I am using Lucene Search for my website....

I am using default indexSet to search which is something like this....

<IndexSet SetName="InternalIndexSet" IndexPath="~/App_Data/Internal/">
      <IndexAttributeFields>
        <add Name="id" />
        <add Name="nodeName" />
        <add Name="updateDate" />
        <add Name="writerName" />
        <add Name="path" />
        <add Name="nodeTypeAlias" />
        <add Name="parentID" />
      </IndexAttributeFields>
      <IndexUserFields/>
      <IncludeNodeTypes/>
      <ExcludeNodeTypes />
    </IndexSet>

I just want to add what is IndexUserFields..... wht kind of properties can be added there ? ....
