Diversity in Stock Photos

Wow, I have this exact same request, and my biggest frustration is not the lack of photos, but the lack of advanced search options. It seems like if I search for "business diversity" I get results for business OR diversity, but not both, even if I put the phrase in quotes. And why did I get an image of a guy on a motorcycle and another of a drone flying over a field in those search results? It would also be nice to have a "more like this" button, where you can identify a picture that is getting closer to what you want and have the system search for similar images - preferably not necessarily visually similar but similar in keywords. 

Having a single search field seems like the main problem to me. If you have millions of images, you MUST have advanced search options. 

To be clear, I'm very happy to have access to such a large library, but the value of it is greatly diminished when you can't effectively find what you need. I'm going to experiment with Boolean searching, but I definitely would like to put my name in for any enhancement request that involves advanced search options. Thank you!
