search VCM Index Channel using V7 Portlets?

Hi,

We have created some index channels (Similar types of content are best displayed through the use of index channels. Index pages then display a compilation of links to content. All types of content can be associated to an index channel except image.) in VCM. We have lots of index channels in different sites, Its very difficult to check it manually.
So, Please help me how to search index channels with path using V7Test Portlets.
