> 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).
