Right. Keyword and other such fields (likely not analyzed) should def be
omitTf and OmitNorms, unless you have some special situation.

Yes, that was may opinion when reading the java docs. I wanted to be sure.
In principle we could write down somewhere, that disabling norms is good for
not-analyzed fields like document identifiers, numbers,.... Such a field do
not need norms, as e.g. the document identifier is only used for searching
for only the document or sorting or something like that. So in my opinion,
the best default for non-analyzed fields is to use no norms, right?

Subject: Re: Question on small optimization in TrieUtils
It shouldn't have an affect, I'd make the change. The norm setting is
only respective to the field you set it on, and a sort field won't
benefit IMO. Norms are for index time boost and field length
normalization right? Turn them off I say.

Hi,
I was just looking through some more optimizations of my trie encoded
fields. They are currently indexed using omitTf. Additionally I could
also
add omitNorms to the index options for such type of fields (because they
are
only used for sorting and the special TrieRangeFilter). Does this has
any
effect on other fields and boosting when used together with normal
TermQueries? If no, I commit shortly!
