Expert: Index the tokens produced by running the field's value through an Analyzer, and also separately disable the storing of norms. See NOT_ANALYZED_NO_NORMS for what norms are and why you may want to disable them.

The "Expert" note means that ordinary non-expert users like me should
not be using it directly.  It will likely be called behind the scenes
by some other method not flagged as expert, and it is those that we
should be using.  Only developers and clever people doing clever
extensions and the like would be expected to use the expert methods
directly.
