> SOLR-10186
> [~erickerickson]: Is there a good reason that we hard-code a 256 character limit for the CharTokenizer? In order to change this limit it requires that people copy/paste the incrementToken into some new class since incrementToken is final.
> KeywordTokenizer can easily change the default (which is also 256 bytes), but to do so requires code rather than being able to configure it in the schema.
> For KeywordTokenizer, this is Solr-only. For the CharTokenizer classes (WhitespaceTokenizer, UnicodeWhitespaceTokenizer and LetterTokenizer) (Factories) it would take adding a c'tor to the base class in Lucene and using it in the factory.
> Any objections?
