34e2f7f487 enhanced snippet fetch strategy: concurrent snippet fetch even for offline-snippet searches. This improves speed since it is now possible to fetch snippets offline and parsing of source files from the htcache can be enhanced using concurrency. This improves local and remote search.

348dece62f redesign of the SortStack and SortStore classes:
created a WeakPriorityBlockingQueue as special implementation
of a PriorityBlockingQueue with a weak object binding.
- better abstraction of ordering technique
- fixed some bugs according to result numbering (distinguish different counters in Queue)
- fixed a ordering bug in post-ranking (ordering was decreased instead of increased)
- reversed ordering numbering using a reversed ordering. The higher the ranking number the better (now).

11b7853940 added a configuration page for search heuristics. currently you can switch on there:
- a site-operation heuristic that loads all direct links from a portal page if the site-operator is used
- a direct crawl for search results from scroogle for the given search terms
The configuration page can be found directly beside the network configuration page

60e71876ad - more abstraction (HashMap -> Map)
- more concurrency-awareness (HashMap -> ConcurrentHashMap)

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

1e8e79b9ef redesign of reference hash (URL-hash) parameter hand-over:
pass value as byte[], not as String. This should cause that less
byte[] <-> String conversions are made during time-critical tasks.
This redesign is not yet complete, more to come ..

4a5100789f replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.
