Search screenshot text with spotlight

When I take a screenshot I thought it might be good to be able to search the textual content in the screenshots. My favorite Mac automation app Keyboard Maestro has an OCR function which I used to monitor my screenshots on my desktop folder and then run optical character recognition on the screenshots. After the macro has the text in English, Chinese (Traditional and Simplified) it stores the text in the file comments.
