Adrien Grand commented on LUCENE-8870:
--------------------------------------
I think this new constructor would be misleading. For instance it might be
tempting to use if you wanted to index doubles. But the only thing you can
index with this constructor is the string representation of the double values,
which is unlikely to be helpful.
I wonder whether we should make this class abstract instead so that it can't be
instantiated directly, and potentially enhance some of its sub classes to
address use-cases that were only doable with this Field class until now, such
as having a text field with term vectors enabled.
