I just noticed that WordPress seems to use two different ways of providing users with search results.
First the site.com/index.php?s=searchterm structure, and then site.com/search/searchterm/ structure.
Is there any particular reason for this? I'm asking because the second url structure may get indexed by search engines which may result in duplicate content and all that good stuff that goes along with it.
My question is this: Would you suggest to block /search/ from being indexed by search engines? Or, would you have another suggestions on how to deal with the issue?
