SeedDB.lookupByName searche for lowercase peerNames, while MapColumnIndex.getIndex uses peername as is in the keyset.
Changed the index init to insert lowercase peer names as key
- Changing the format of YaCy's solr.key.list while maintainig backward compatibility
Federated index config screens adjusted accordingly
- modified the Solr update request to use a 3 min Solr autocommit intervall
Error was:

queue and not from virtual documents generated by the parser.
- The parser now generates nice description texts for NOLOAD entries
which shall make it possible to find media content using the search
index and not using the media prefetch algorithm during search (which
was costly)
- Removed the media-search prefetch process from image search
only links where the content can be parsed. All non-parseable links are
placed into the noload queue. The search process must therefore be able
to filter out non-text search results.
- This fixes the problem that image search results appeared in the text
search.
- The interactive search can retrieve now ALL types of links
- The p2p interface is now extended to retrieve only certain types of
links (text, image, video, apps)
- The search process has an extension to filter the right document type
according to the search query
- a new database for url reference data ('seen links')
- a new database extending the references to the full url metadata
attributes set which shall replace the old metadata database if it is
finished
- migration help classes stub to use old and new metadata databases
simultanously
the links between all pages are now stored. The same index structure as
used for the word index is used to make a reverse link index.
The new file(s) in SEGMENT/default/citation.index.*.blob store the
citation index. This will be used to create much more detailed link
structures for the YaCy apis and to create a better ranking. A ranking
using the citation.index should provide better results especially for
portal indexes and initranets.

long t = System.currentTimeMillis();
for (int i = 0; i < c; i++) {
q.add(q.size());
}
return System.currentTimeMillis() - t;
}

Runtime.getRuntime().gc();
long t2 = countTest(new LinkedBlockingQueue<Integer>(), c);
Runtime.getRuntime().gc();
long t3 = countTest(new ConcurrentLinkedQueue<Integer>(),
c);
System.out.println("count = " + c + ": ArrayBlockingQueue =

c = c * 2;

1. Improved and fixed language detection:
1.1 Identificator.java - recognition fix (improved)
1.2 DCEntry.java - fix (changed detection order due to detection from
tld in many cases is incorrect)
1.3 MultiProtocolURI.java - fixed and enhanced language from tld
detection (all currently used top-level domains; ccTLD added but not
tested).
2. Ukrainian language update.
3. Main Slavic languages langstats (tested and works fine).
ready-prepared crawl list but at the stacks of the domains that are
stored for balanced crawling. This affects also the balancer since that
does not need to prepare the pre-selected crawl list for monitoring. As
a effect:
- it is no more possible to see the correct order of next to-be-crawled
links, since that depends on the actual state of the balancer stack the
next time another url is requested for loading
- the balancer works better since the next url can be selected according
to the current situation and not according to a pre-selected order.
