acrobat and SDK and indexing

I have just recently downloaded Acrobat DC Pro because I was told it came with the SDK and the SDk could handle the task I was looking to perform. The bottom line is I am trying to index a PDF file without opening it in Adobe acrobat. I have spent the better part of the week researching this and I'm struggling to make a lot of progress, so I have a few questions.

Can someone point me to some examples of using the SDK to index a PDF file.  I'm not a javascript or C# developer but have enough programming experience to figure it out once I get started.

Best suggested way to accomplish my task? Javascript? C#? Plugins? or Windows Interapplication communications?

Lastly? It only looks like I can create a full text catalog (pdx) on the PDF file through the SDK - is that correct? Why did adobe change to have embedded indexes diabled by default?

Sorry for the ramblings but any help / suggestions would be greatly appreciated.

Thanks ,Joe
