- one word prototype is generated for each document, that is re-used when a specific word is stored.
- the index cache uses now ByteArray objects to reference to the RWI instead of byte[]. This enhances access to the the map that stores the cache. To dump the cache to the FS, the content must be sorted, but sorting takes less time than maintenance of a sorted map during caching.
