From the post:
Using Custom Search Engine (CSE), you can create rich search experiences that make it easier for visitors to find the information they’re looking for on your site. Today we’re announcing two improvements to sorting and filtering of search results in CSE.
First, CSE now supports UI-based results sorting, which you can enable in the Basics tab of the CSE control panel. Once you’ve updated the CSE element code on your site, a “sort by” picker will become visible at the top of the results section.
I am not sure I would call this a “rich search experience” but I suppose any improvement is better than none at all.
Curious how you evaluate the use of “product rich snippets” as being similar to Newcomb’s conferral of properties? (see the post for “product rich snippets”).
Or for that matter, how you would in an indexing context, “confer” additional information on an index entry that does not appear in the document?
To be used when the index is searched.
