This is the array for my arguments for the WP_Query.
Array ( [showposts] => 4 [paged] => 1 [post_type] => post [post_content] => tree [category__and] => Array (  => 6  => 15  => 28 ) )
I want to return the posts where they are in the categories 6, 15, 28 and where the post_content has the word tree.
My problem is that I'm returning several duplicated results for the posts that have the word tree in it. Ideally I would like to return one.
anyone have any idea how I can fix or improve this?
