Why does your search function sometimes ignore exact matches that exist in your system

If I search "Gone" I do not get all the choices available with that title. If I search the star (Molly Parker) a listing for Gone is prominent on her list of films. This is the most vivid example I can recall in which your search engine kicks up references that are modern and/or popular rather than what I'm looking for with the precise title. Gone is just as example of this. This never used to happen. If you typed a specific title or name of an older or more obscure film or actor you got the listing. This does not happen now and it's probably because of something your programmers have done. It seems to me to be an unwise move. If I have the exact title for a film in your listings it should be presented in the search field. I shouldn't have to click on other titles or whatever it is to find what I'm looking for. You can throw up some other results that are of more interest to you if you want, but you should not hide the specific connection on purpose. Thanks for your time.
