New block link style in search results

We are testing a new link style that turns the extract for a page into a block. The block has a few features that enhance the search results:

• As a user moves their pointer over the block, the block is highlighted.
• While the pointer hovers over the block, the block expands to show more sentences containing the search terms (if any).
• Clicking anywhere in the block brings up the matched document.

The new link style is #3, thus to use it add "/link3" to your search URL. During testing it will be available only in our test search engine, nquery. (That is, use nquery in place of query in your search URL.) You can try it out by searching this blog!
