The wiki on the new broad search setting says it "will incorporate datatypes, headwords and words with values that are equivalent to your value. For example: “God the Spirit”, “Comforter” and “Paraclete” would be used in addition to “Holy Spirit”."
Yet when I run a search of "spirit" in the gospel of John it doesn't return other forms (i.e. Advocate from John 15:26)
Am I misunderstanding how this is to work?
