Allow Grow to power search features on your site, both as an option in the Grow widget and powering your native search box on your site.
The search icon is a feature that doesn't require a reader to be logged in. (Although, that is the goal!) Clicking this will pull up a search area to quickly search for posts on a site.
A reader can click on the results to view the post, but can also bookmark or share straight from the search results.
What are the Options and Where Do I Enable?
There are two options under the search feature that you can enable in your Dashboard > Grow (Beta):

1 - Search: This is the setting that allows the search option to display in the Grow widget:

2 - Site Search Integration: allows Grow's search to integrate with your site's native search box.
