Search Results Page

On the Search Results Page: 1) How do I remove some of the white space between results? 2) Every now and then I notice that the 'Read More' doesn't show up on a post in the Search Results page. Notice on the "botox for jowels...' post: http://hidemyage.staging.wpengine.com/?s=botox&submit=Search I have gone into that particular post and I applied the Read More in the same fashion as all the other posts so I don't get it. 3) How can I add a thumbnail for each post on the Search Results Page? Thanks!!! Kim
