I'm trying to search for a scientific review article of determined theme. That is, I'm not searching a single scientific article containing an analysis of a determined theme, I'm trying to search a scientific article containing a review of many articles about the theme and its conclusion.
What are the terms which I should include in my search (using Google)? Example: "free trade revision", or "free trade paper review"... what are the recommended terms for this search?
Extra question: What are the best sites to search about this? (scientific reviews, scientific articles, papers, books, etc..)
Note: I think my English is legible, I'm brazilian.
