We recently have developed a new plugin to replace the NopCommerce Search mechanism with the Google Custom Search engine.

Support for:
-endless scrolling (auto paging) through search results
-storage of search terms
-fully adjustable to your own website styling. Customers won't see the difference
-no Google styling
-support form multi store configurations (independent api keys)
-support for both free Google search as well as paid Google search api.

We are thinking of making this a commercially available plugin for all NopCommerce versions 3.5 - 4.2.

Before we do that, we would like to know if there is any need for such a plugin and what would be an acceptable price.

I'll keep an eye on the postings to this topic.
Cheers
