Field creation with TokenStream and stored value
Hey out there,
in lucene it's not possible to create a Field based on a TokenStream
AND supply a stored value.
Is there a reason why a Field constructor in the form of
public Field(String name, TokenStream tokenStream, String storedValue)
does not exist?
I am using trees of TeeSinkTokenFilter's for the creation of many
fields, based on a source string.
That's the reason why I can't use the "standardconstructor"
public Field(String name, String value, Store store, Index index)
Regards
Benjamin

Actually, you can implement your own Fieldable, and return what you want
from its methods. You can also use Field constructor that takes the
stored value, and then use Field.setTokenStream(TokenStream) - it
doesn't override the stored value.

Thanks!
Didn't know that it's so easy ;)

Why not simply add the field twice, one time with TokenStream, one time stored only? Internally stored/indexed fields are handled like that.

Sorry for pushing this thing.
Would it be possible to add the demanded constructor or would it break
anything of lucenes logic?
