When searching, for example, for Movies like «Ocean's Thirteen» remember that «13 or «Thirteen» gives different results, also «Ocean» is the same as «Ocean's» but it might be written like «Oceans» which will not appear in a Search for «Ocean». So all these Searches will give different results: «Ocean's Thirteen», «Ocean's 13», «Oceans Thirteen», «Oceans 13». Besides all this, the best way to Search for a Movie or TV-Series is the IMDB personal link. For the previous example search for «tt0496806».

Also, adding the year in the search along the name of the Movie is a good option.

Still, remember that, after doing a normal Search you have the option for «Advanced Search». Just clean what you have entered at the field just above «Enter your keywords» and use the new fields and options to refine your Search.
