Robert Muir commented on LUCENE-5870:
-------------------------------------
I am a little concerned about this, since it results in loss of information.
its similar to the parallel of removing TOKENIZED bit from stored fields before
but yet still keeping StringField. This caused a lot of confusion for users.
Today, the Analyzer doesn't know have "full picture" because of
StringField/IntField/FloatField and company "bypassing it". This causes a lot
of pain, for example, you cannot even do a simple numeric range query with
lucene without subclassing things with your "own additional schema".
In my opinion this stuff makes lucene too hard to use, because its too hard to
reconstruct the doc from stored fields to e.g. perform an update to it and pass
it back to indexwriter. Instead it tries to force people to either
write/maintain a separate schema and subclass many things or force them to use
some server that does this, which should not be necessary.
An alternative would be, if we removed StringField/IntField/LongField etc and
these were instead just KeywordAnalyzer/IntAnalyzer whatever in the analysis
chain, then queryparser could form range queries without subclassing, queries
on string fields would just work, and the "schema" needed to search would be
implicit all in one place (the users Analyzer), making lucene a lot easier to
use.

> StoredFieldVisitor has a visitor method for 4 numeric types: int, long, float
