terms (words) are not any more retrieved by their word hash string, but by a byte[] containing the word hash. this has strong advantages when RWIs are sorted in the ReferenceContainer Cache and compared with the sun.java TreeMap method, which needed getBytes() and new String() transformations before. Many thousands of such conversions are now omitted every second, which increases the indexing speed by a factor of two. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5812 6c8d7289-2bf4-0310-a012-ef5d649a1542
