Search a photo/video/file through the comments

For example. Lets say I have a like 20+ photos out of 1000+ and in the comments of those photos they have the word "red" in them. The Ability to search through your photos etc. using the "comments" as the "filter" there would be a search bar and I type the word "red" and it brings up all my photos with the word "red" in the comments. I hope that makes sense.
