Exclude posts that belong to a category 排除职位，属于一类

Maybe you don’t want posts from a certain category showing up on your index or another archive page.也许你不想员额从某一类出现在您的索引或其他存档页。 You could even use this to keep certain categories from showing in search results if you needed to.你甚至可以用它来保持某些类别显示在搜索结果中如果你需要。 You need to know your category “ID” to do this, just retrieve it from your dashboard under “Manage->Categories”, and the “-1″ with your category ID# like this…您需要知道您的类别“编号”要做到这一点，只是找回它从您的仪表盘下的“管理”类别“和” -1 “与您的类别编号：像这样...
