With "Auto new search with stems if nothing found" checked if a term is searched for and is not found, then the search will automatically be repeated with a wild card (*) before or after the term specified. If the term is found then the wild card search is not done. Note that "term" here means individual word, not phrase, since only words are indexed.
With the word "bee" not being found, I would suspect that it is in the stop list of frequent words and thus is ignored in searches. Wax would be less common and probably is not in the stop list. (By default neither bee nor wax are in the stop list) You can edit the stoplist under Preferences > Search Settings > Search indexing.
