In Google Images, one can normally specify an image format, for example let's say I want PNGs; then I can type
filetype:png my search terms.
Today, I wanted to search for some vector graphics so I tried
filetype:svg my search terms. However, Google Images completely ignored it and returned the results I'd get for
my search terms, without the type restriction.
So, the question is, how to search for vector graphics in Google Images? If it's not possible, what else can I use?
