Whenever I look for a certain file type, there are certain extensions that are always useless and fake, ie. .asx, .wmv. In order to increase the likelihood of finding what I want, I've entered these extensions into the keyword filter. However, some extensions it seems to be ignoring. I entered .wma, because I don't want them, but the filter still lets them through, in great numbers, clogging the results, making it hard to find something I want. Does anyone know how to fix this?
