Simon Willnauer commented on LUCENE-2308:
-----------------------------------------

bq. Second time this morning you didn't even read what I said.
I did but apparently we talk about different things? the entire purpose of FT is that you don't have to create it multiple times so folks can create Field each time but they should reuse FT, no? I personally talk about createing FT using a builder but what uwe says is we can also do that for field though. 

Again how do you create way more object when you use a builder than when you use the ctor?

> 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...
