John Roesler f86e8c33c1 Docfix: ignore_above uses string length, not utf-8
ignore_above is used to guard against the lucene limitation
that a term cannot exceed 32766 bytes.

However, the implementation just used the character count, which
doesn't take into account the fact that some characters have
multi-byte utf-8 encodings.

This commit updates the docs to make this relationship clear.
