请分析一下这个英文句子的主谓宾语分别是什么?
As you can begin to see,filters are not restricted to categories of applications but,depending on what the lens is,may select results by a number of other categories,such as Rating and Sources in the Applications lens.
这个句子很长,而且but接在那个applications后,让我分不清这个句子的主语、谓语、宾语在哪,因而不好理解整句.（该句源自一本介绍ubuntu系统的英文书）
