Chris Male commented on LUCENE-2308:
------------------------------------
I will make the appropriate javadoc changes right now.

Should we also move numeric(), numericDataType() and maybe
docValuesType() into oal.index.FieldType? (We can do this as a
speparate issue though).
{quote}
Yup.
{quote}
I also like Marvin's/Robert's suggestion of using int flags for all
these booleans (also a separate issue!).
{quote}
I like them too. Lets do that.
{quote}
Maybe name oal.index's FT to IndexableFieldType? And then drop Core from
oal.document's? Ie, oal.document.FieldType and
oal.index.IndexableFieldType? (Aren't we going to shortly need
oal.index.StorableFieldType?).
{quote}
Good idea. Its going to reduce this patch size considerably.

> This came up from dicussions on IRC. I'm summarizing here...
> Today when you make a Field to add to a document you can set things
> index or not, stored or not, analyzed or not, details like omitTfAP,
> omitNorms, index term vectors (separately controlling
> offsets/positions), etc.
> I think we should factor these out into a new class (FieldType?).
> Then you could re-use this FieldType instance across multiple fields.
> The Field instance would still hold the actual value.
> We could then do per-field analyzers by adding a setAnalyzer on the
> FieldType, instead of the separate PerFieldAnalzyerWrapper (likewise
> for per-field codecs (with flex), where we now have
> PerFieldCodecWrapper).
> This would NOT be a schema! It's just refactoring what we already
> specify today. EG it's not serialized into the index.
> This has been discussed before, and I know Michael Busch opened a more
> ambitious (I think?) issue. I think this is a good first baby step. We could
> consider a hierarchy of FIeldType (NumericFieldType, etc.) but maybe hold
> off on that for starters...
