title_body: Organizing a lexicon in a logographic writing system
upvoted_answer: Having a dictionary ordered by theme or idea is a good thing and it can carry you a long way in the design of your writing system.
  
  For a more systematic approach, you need a way to order your logograms. Chinese sorting may be an inspiration for you. They identify a "radical" in each character, and than order by radical + number and order of additional strokes. The approach has the advantage that simpler characters (with fewer strokes, and probably more frequent usage) come before more complex ones.
