Could google scholar replace other search engines?

[inempty]

We have many engines to search the literature, such as sciencedirect and so on. And we also have google scholar to search the whole literature. Is it a good idea to use only google scholar since it looks complete enough? What's your opinion?

Maybe. I prefer sciencedirect when I know what I'm looking for usually quicker with sciencedirect than with scholar google, which finds a lot more, but you may have to scan more before you spot the right one.

Example scholar google, http://www.sciencedirect.com/science?_ob=ArticleListURL&_method=list&_ArticleListID=2114646922&_sort=r&_st=13&view=c&_acct=C000228598&_version=1&_urlVersion=0&_userid=10&md5=ab20e21c528f0d319114a661083d5053&searchtype=a

Nopes. It also does not find some articles.
