Analytic Feature

[twf-nikhila]

We're using this plugin, works great for our documentation needs.

One thing we feel missing is Analytic, will be nice to have analytic like:

1. Search Terms in documentation: This will help to add those docs missing or add search keywords if document is present but with different wording. 2. Top docs on "Was this article helpful?" Yes or No: Will help to improve the document with low rating.
