31283ecd07 - added a search option to filter only specific network protocols. i.e. get only results from ftp servers. Just add '/ftp' to your search.
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

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
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.

b45701d20f this is a re-implementation of the YaCy Block Rank feature
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.

8f11d3a5bb redesigned the ScoreMap classes:
- 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

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

9b25a33fd9 - fixed numerous bugs
- 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.

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.

cc6499bf8d - added http://blekko.com as search heuristic (like scroogle). This was easy since they deliver their search results also as rss feed
- 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

a9f754c45f removed unused CR accumulation and distribution process
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

- 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).
