Description

With flex, a term is now an opaque byte[] (typically, utf8 encoded unicode string, but not necessarily), so we need to push this up the search stack.

FieldCache now has getStrings and getStringIndex; we need corresponding methods to load terms as native byte[], since in general they may not be representable as String. This should be quite a bit more RAM efficient too, for US ascii content since each character would then use 1 byte not 2.
