db99db4be9 some redesign of the search-fail-response mechanism:
when a search fails for a single url because the snippet cannot be generated, then the url reference is deleted from the index. This mechanism was redesign and enhanced. The process now also writes into the work tables into the table searchfl to prepare a re-indexing mechanism.

7cd9d9d22a - enhanced DidYouMean computation using a faster count on index entries; this causes that results can be ranked better
- added limitations on DidYouMean result sets according to input and output string length

6388a58fc7 better memory management and slightly less (in total and temporary) RAM allocation:
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth
- changed index sorting method in such a way that it allocates less objects during quicksort
- database classes classes renaming (shorter, naming addresses that objects hold in RAM)
- added a large number of asserts to check if objects actually take the RAM that they should have

90c3e5d6f6 - cleanup, removed unused imports
- added crawling queue sizes to /api/status_p.xml, syntax same as in queues_p.html
- fixed a bug in queue enumeration that caused a out of bounds exception

93ea0a4789 enhanced remove operation in search consequences (which are triggered when the snippet fetch proves that the word has disappeared from the page that was stored in the index)
- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

8b8107b2a3 reduced IO-load and synchronization/blocking
- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

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)

650be3599f added a time-out to the RWI cache to flush the cache if it has not been written for ten minutes. This additional dump criteria is necessary because some data sources repeat their vocabulary and may cause that the number of words in a RWI does not increase while the number of references in the RWI set increases. Now the RWI Buffer is flushed every 10 minutes or later if at that time already a dump is ongoing.

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 ..

749ffbd642 - added another catch case for the index dump and index merge process that should cause non-blocking behavior in case that index dump and/or index merge caused any unexpected exception.
- reverted SVN 6766, this is too dangerous (may cause unexpected memory usage) and should not be necessary

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.
