Would that be equivalent to
Document doc = new Document();
Field f = new Field("body", bodyText, Field.Store.NO
,Field.Index.NO_NORMS);
And Field.Index.TOKENIZED has no effect after f.setOmitNorms(true); ?
Yes, those two have the same effect.
I don't think so - these two scenarios are different.
When you create a Field using Index.NO_NORMS, the constructor makes sure
that:
isIndexed = true;
isTokenized = false;
omitNorms = true;
When you create a Field using Index.TOKENIZED, the constructor sets
these flags:
isIndexed = true;
isTokenized = true;
Then, when you call setOmitNorms(true), it does NOT affect isTokenized,
it sets only omitNorms. So the flags are set now like this:
isIndexed = true;
isTokenized = true;
omitNorms = true;
The end result of processing such a field is (I believe) conceptually
equivalent to adding as many Fields as there are tokens, each with
omitNorms=true.
