This search is on a simple character match. If what you look for isn't exactly as you type it, including punctuation, it won't find it. I'm working on developing a more intelligent search. In the meantime I suggest using simple searches. If you do Scripture lessons try using only the book and chapter (e.g. Mark 10, Psalm 23, etc.). Also, when searching for Scriptures, do not use abbreviations, the references in the database are all based on the full book name.
