完成工作：
调研了microsoft academic research, 貌似现在还没有发布API。不过提供了一个query规则。
You could also perform advanced searches in normal search field with structured queries. You may refer to the Structured Query Language as follows:
<query> := <tokens>+ <token> := <normal query> | <field query> <normal query> := (array of any non-white-space character) <field query> := <key><oper><field query value> <key> := 'author' | 'title' | 'conf' | 'jour' | 'year' <oper> := '>=' | '<=' | ':' | '=' | '>' | '<' <field query value> : <normal query> | '(' <normal query>+ ')'
如果使用microsoft academic research，那么我们很可能需要parse搜索返回的html。
计划明天工作：
尝试一下从microsoft academic research里面扒网页的效果如何。。。
