The export-feature is optional, the purpose of that function is to provide a back-up function for URLs to be deleted. The export function can also be used to create html files with embedded links and simple text-files. Simply replace the 'xml' word with 'html' or 'text'. The last argument in the cann, the diffurlcol.dump value, can also be omitted. This will cause that the complete URL database is exported. This is an alternative to the Web-Interface based export function.
The delete-feature is the only destructive method of the four presented here. Please use it with care. It is better to make a back-up of the url database files before starting the deletion.

to use this, you must user the -incollection command before (see SVN 5687) and you need a
used.dump file that has been produced with that process.
Now you can use that file, to do a URL-hash compare with the urls in the URL-DB. To do that, execute
java -Xmx1000m -cp classes de.anomic.data.URLAnalysis -diffurlcol DATA/INDEX/freeworld/TEXT used.dump diffurlcol.dump
or use different names for the dump files or more memory.
As a result, you get the file diffurlcol.dump which contains all the url hashes that occur in the URL database, but not in the collections.
The file has the format
{hash-12}*
that means: 12 byte long hashes are listed without any separation.
The next step could be to process this file and delete all these URLs with the computed hashes, or to export them before deletion.

- after a index selection is made, the index is splitted into its vertical components
- from differrent index selctions the splitted components can be accumulated before they are placed into the transmission queue
- each splitted chunk gets its own transmission thread
- multiple transmission threads are started concurrently
- the process can be monitored with the blocking queue servlet
To implement that, a new package de.anomic.yacy.dht was created. Some old files have been removed.
The new index distribution model using a vertical DHT was implemented. An abstraction of this model
is implemented in the new dht package as interface. The freeworld network has now a configuration
of two vertial partitions; sixteen partitions are planned and will be configured if the process is bug-free.
This modification has three main targets:
- enhance the DHT transmission speed
- with a vertical DHT, a search will speed up. With two partitions, two times. With sixteen, sixteen times.
- the vertical DHT will apply a semi-dht for URLs, and peers will receive a fraction of the overall URLs they received before.
with two partitions, the fractions will be halve. With sixteen partitions, a 1/16 of the previous number of URLs.
BE CAREFULL, THIS IS A MAJOR CODE CHANGE, POSSIBLY FULL OF BUGS AND HARMFUL THINGS.

The cache is now flushed only for one second every ten seconds. During a crawl the cache
fills up completely, and is only flushed if space is needed for more documents.

this is a migration step to support a new method to store the web index, which will also based on the same data structure. made also a lot of refactoring for a better structuring of the BLOBHeap class.

- modified and activated write buffer
- increased cache flush factor
- fixed a problem with deadlocking of indexing process

- removed never-used secondary crawl depth
- added a must-not-match filter that can be used to exclude urls from a crawl
- added stub for crawl tags which will be used to identify search results that had been produced from specific crawls
please update the yacybar: replace property name 'crawlFilter' with 'mustmatch'.
Additionally, a new parameter named 'mustnotmatch' can be used, which should be by default the empty sring (match-never)

- implemented vertical DHT acceptance ("my own DHT") to accept new targets
- added new target computation for global search: addresses vertical targets also
- enhanced remote crawling: collection of remote crawl urls if queue has less than 100 entries (was: 0 entries)
- better performance value computations for PPM selection in network configuration

with index.storeCommons=false all currently stored commons are deleted!
Default is now 'true', but in future full releases it will be switched to 'false'

- balancer writes cause of robots.txt in log file for crawl delay
- removed log output for forced GC
- smaller RAM flush for RWI cache, should cause more usage of cache and faster crawling
