for example search for "passwd /ftp". This can also be done with /http /https and /smb
- fixed some search throttling processes that should protect your peer against search DoS or strong search load

results sorted out by add to RankingProcess were counted in
sortedout-counter, but were not added to remote_indexCount nor
local_indexCount

used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

- many speed/performance hacks
- added solr charding and new charding web interface
- added option to switch off the yacy index when using solr
- added new fail-url categories which are used to make a distinction which fail-urls to be sent to solr
- refactoring/renaming of some method names to distinguish host/url hashes better
- a large number of bug/npe fixes

This time it works like this:
- each peer provides its ranking information using the yacy/idx.json servlet
- peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob
- this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable
- I computed new ranking tables as part of the distribition and commit it here also
- the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers
- a recursive block rank refinement is implemented but disabled at this point. it needs more testing
Please play around with the ranking settings and see if this helped to make search results better.

- new concurrent score map using atom operation from java concurrency classes
- redesigned difference beween StaticScore and Dynamic Score into ScoreMap and ReversibleScoreMap allowed that many classes can now use simple ScoreMap Objects which can be used better in concurrent environments using the ConcurrentScoreMap
- switched from DynamicScore to ConcurrentScoreMap usage wherever possible

- better document names
- fixed problem with ftp crawling
- added automatic removal of search results from services that are not online according to the latest network scan: this does not delete the index but just does not show them. after the next network scan when the server is available again, the results are again showed.

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.

- renamed YaCys search result modifications keywords for RECENT, NEAR and language: to the blekko slashtag naming scheme. YaCy now supports the following blekko-like slash built-in slashtags:
/date
- for search results ordered by date (most recent up)
/near
- for search results where search words appear near to each other (closest up)
/language/<lang>
- for a sorting by language where the wanted language gets up. Example: /language/de

this was never used and extended in the last years. The resulting YBR ranking criteria
is still a good idea and will be used in the future. Possible generation methods for YBR
ranking are:
- "trust-rank" using the link structure as can be discovered in a single crawl (idea from FSCONS)
- "block-rank" calculated from the local link structure
- a distributed "block-rank" using the xml API to the link structure from other peers

- better control of number of running search threads
- no time-out waiting time when no ranking feeding takes place
- local search queries by a remote peer may be faster up to 300 milliseconds
- a local search may even be faster

- changed data structure for sorting in search which performs better in that specific case (too many updates)

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).

- it is now possible to crawl the local file system with an intranet peer
- redesign of URL handling
- refactoring: created LGPLed package cora: 'content retrieval api' which may be used externally by other applications without yacy core elements because it has no dependencies to other parts of yacy

- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)
