> During updating my internal components to the new TrieAPI, I have seen the following:
> I index a lot of numeric fields with trie encoding omitting norms and term frequency.
This works great. Luke shows that both is omitted.
> As I sometimes also want to have the components of the field stored and want to use the
same field name for it. So I add additionally the field again to the document, but stored
only (as the Field c'tor using a TokenStream cannot additionally store the field). As it is
stored only, I thought, that I can left out explicit setting of omitNorms and omitTermFreqAndPositions.
After adding the stored-only-without-omits field, Luke shows all fields with norms enabled.
I am not sure, if the norms/tf were really added to the index, but Luke shows a value for
the norms and FieldInfo has it enabled.
> In my opinion, this is not intuitive, o.a.l.document.Field  should switch both omit*
options on when storing fields only (and also disable other indexing-only options). Alternatively
the internal FieldInfo.update(boolean isIndexed, boolean storeTermVector, boolean storePositionWithTermVector,
boolean storeOffsetWithTermVector, boolean omitNorms, boolean storePayloads, boolean omitTermFreqAndPositions)
should only change the omit* and other options, if the isIndexed parameter (not this.isIndexed)
is also true, elsewhere leave it as it is.
> In principle, when adding a stored-only field, any indexing-specific options should not
be changed in FieldInfo. If the field was indexed with norms before, norms should stay enabled
(but this would be the default as it is).
