Earwin Burrfoot commented on LUCENE-2308:
-----------------------------------------
I'm strongly against names like 'matchOnly'. They are perfectly fine in some
'schema' layer over Lucene, but here, in lowlevel guts, I'd prefer names that
clearly state what the hell do they do, without forcing me to consult
javadocs/code.
> Separately specify a field's type

> Key: LUCENE-2308
> URL: https://issues.apache.org/jira/browse/LUCENE-2308
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index
> Reporter: Michael McCandless
>
> 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...
