like normal documents. Using this option (by default on at this moment;
this might change soon) it is possible to get the exif data into the
search index to be used in image search.
regular expression on th url: the collection attribut for a crawl start
may be now either a token or a list of tokens, seperated by ',' where a
token is either a string or a pair <string,pattern> where the string is
separated to the pattern with a ':' and the string is assigned to the
document as collection only if the pattern matches with the url.
in intranets and the internet can now choose to appear as Googlebot.
This is an essential necessity to be able to compete in the field of
commercial search appliances, since most web pages are these days
optimized only for Google and no other search platform any more. All
commercial search engine providers have a built-in fake-Google User
Agent to be able to get the same search index as Google can do. Without
the resistance against obeying to robots.txt in this case, no
competition is possible any more. YaCy will always obey the robots.txt
when it is used for crawling the web in a peer-to-peer network, but to
establish a Search Appliance (like a Google Search Appliance, GSA) it is
necessary to be able to behave exactly like a Google crawler.
With this change, you will be able to switch the user agent when portal
or intranet mode is selected on per-crawl-start basis. Every crawl start
can have a different user agent.

jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger
yacy will load linked web pages from search results until the total
number of web pages reaches 15000. This shall give fresh peers a 'boost'
to get faster a personalized search index.
soft commits, reduced caching size of search events, ensured that solr

too long in RAM
id to be tested, but with a collection of ids. This will cause only a
single call to solr instead of many. The result is a much better
performace when testing the existence of many urls. The effect should
cause very much less IO during index transmission, both on sender and
receiver side.
process counter if an blocking thread dies. Added also a new column in
PerformanceConcurrency_p servlet to show the actual number of concurrent
processes.
Because the index size is now provided by solr, and the only way to do
that is a match for [* TO *], a size computation is quite complex and
time-consuming. Therefore this patch prevents that the method is called
at all and if necessary puts a DOS-preventing barrier in front of it.
