Oscars and the new advanced title search

The movies which have won special achievement awards on Oscars, for example Return of the Jedi (visual effects) and The Jazz Singer (for its technical achievements), are no longer appearing when we look for Oscar-winning pictures. That also includes all the movies which won the special awards for foreign-language film before the category turns into a competitive category with more than one nominee. Please fix it. These were categories without more than one nominee, but it was the Oscars just the same. In 82 and 84, there were more than one nominee for visual effects, but in 83 the Academy decided that Return of the Jedi has no matches in that category. Just because the award was delivered directly to that movie team, that is no reason to that film to disappear from the lists of winners. Thanks and sorry for my english.
