[2]but此处为介词，意思是“除了……以外”。
[3]这是一个复合宾语，基本结构为“…enables decision makes to search”；“in order to”到句末是目的状语；that引导的定语从句修饰questions。
[4]needing special information是现在分词短语作定语修饰users；从who到句末是定语从句，修饰programer，其中when time permits是时间状语从句。
[5]as a network of…为主语补足语。Developed…and integrated…为并列定语，修饰proceres，for the purpose…为目的状语，to support…为定语，修饰information。
