The search function will check names, comments, synonyms of appearing concepts, and other information for words matching the query. However, it is possible you will still search for a synonym or alternate spelling of something on the OEBP and not find it because the words don't exactly match. Another tool for ease of finding Problems is this index of concepts appearing in Bongard Problems.
Before submitting a Problem, please search for it thoroughly to make sure someone has not already submitted it.
