Here's my feedback.
Cloud search is nice, but it's slowing my site down a bit. Running a Google speed test, I have few errors but Cloud Search is mentioned twice, once somewhat critically:
"Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 4 blocking script resources and 1 blocking CSS resources. This causes a delay in rendering your page. None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Remove render-blocking javascript
:

Next, I'm not quite sure how to leverage this out as I've already done that with Javascript but this one keeps showing up anyway:
"Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources:
