Keyword Search Strategy

No one has come forward with the solution to the Search Challenge posted two days ago.

Admittedly, this is not an easy challenge; probably a Level 6 or 7. To make headway requires search strategies and persistence.

Without giving too much away, here's a strategy that will work:

1. Describe what you see. A close look reveals abbreviated terms such as libre, janit, admin, playg, pk, etc. Taken together, these point to a bigger concept. There's a keyword for that (school). There's also a better word for what the image represents (I'll leave that to you).
2. Other keywords may be derived from the image, e.g., shapes. Most of the elements appear to be some type of hexagons. There's a better keyword than that, but you may not be able to think of it immediately.
3. Test queries. Use the words that you have to look for better keywords. Finding better keywords is a key to this challenge.
4. Know where to look. This is also a key to the challenge. What search engine can you use to locate similar pictures?
5. Keep in mind what you are looking for. Don't expect an answer to be obvious. Look for words and images that share features with the picture. 
6. Use the information you find in new searches to get ever closer.
7. Be persistent. The only way to guarantee you won't find it is to give up. Study snippets and images beyond the first page of results.
