Cheerful keyword only brings back images of women

When using the keywords, "cheerful, bright" only images of women were generated for me Under content, "All" was selected and under styles, "none" was selected. I used the least amount of filters, selectors, keywords, etc. to generate the widest variety of results.

I am wondering why only images of women came back. No fields full of flowers, no kittens or puppies, no rainbows in the skies, not even any cheerful men.
