How much more narrow can you mke a movie search than the actual title????

Point is I get alot of items that is not even close to the title. For example I type in a search for the movie " ****" I may get a couple links for that title but also a whole screen of porn movies and movies of other titles. If I search for "******" then I should not be getting movies such as "*****" or "*****" or "*****" or "*****" How do those pertain to what I was searching for. It is almost like no matter how narrow the search parameters you will get whatever the program decides to give you. With programs like WinMX what you search for is exactly what you get.
