Currently we use the raw byte array length when calling the IndexInput read call to determine how many bytes we want to read. However, due to how BigArrays works, the array length might be longer than the reference length. This commit fixes the issue and uses the BytesRef length when calling read. Additionally, it expands the index follow test to index many more documents. These documents should potentially lead to large enough segment files to trigger scenarios where this fix matters.
