There is no sense in norms for string and numerable fields, but are norms omitted by default for such fields?
I have old schema without "omitNorms=true" and I'm trying to understand, if omitting norms for non-text fields will reduce memory usage.
UPD
I know what are norms about.
I'm asking if norms for non-text fields are omitted by default, or not. Especially, because wiki says, that they are only useful for text fields
