Is there standard way of checking to know whether switching off fieldNorm

If you will *NEVER* care about how the length of a field affects your
relevancy score, you can omit norms for that field. If you don't care
at *all* about how matches in that field affect relevancy, then you
could also omit term frequencies and positions. These settings are
designed to leave standard information out of the index when they are
not required, which makes the index smaller.

Be careful when you decide to leave information out of your
index.Requirements have a way of changing suddenly, and if you're not in
a position where you can reindex quickly, changing your schema for new
requirements is painful, because most schema changes require a reindex.
