This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

- fixes for numerous other problems
- removed dead code
- resdesign of the strings-method, which produces now less memory overhead and may help to prevent OOMs
- another fix for the deadlock problem in SplitTable

- better Exception handling for web cache access
- distinction between access of web cache for proxy and crawler

to make this possible, the yacyURL must be able to process file:// urls, which has also been implemented
testing of the new class resulted in some bugfixes in other classes

the must be downloaded manually by the user and placed in DATA/DICTIONARIES/source
for each externally imported dictionary file there will be a translator that converts the input file once
into a YaCy-internat data format.
Files that will be provided together with yacy releases may still be placed in <root>/dictionaries

- some redesign of DidYouMean that was necessary to follow
a special rule how a library should be used:
- the library provides words that start or end with a test
word which may be possibly also an empty set of words
- all words that the DidYouMean produced with the four
production rules are used to generate a set of
library-completed words
- if this process results in any words from the library,
only library-genrated words are taken
- if the is no library-generated word at all, take the
artifial generated word
- all words that result from these rules are tested against
the index
- the result is ordered using a lightweight comparator that
prefers short words
- a not-so-much-io test against the index is beeing prepared
next
- insered the library initialization into the switchboard

- less pages are fetched in advance
- just-in-time fetch of next required pages
- fix for missing hand-over of offset to fetch threads

this will cause better computation speed for single- and multi-core;
there are enhancements that will speed up old and slow machines as well
as multi-core CPUs. Indexing of surrogates has been speed up
from 4000 PPM to over 20000 PPM on a simple dual core office computer.
Since the enhancements are mostly in core routines, the hack should also
speed up search performance.

this is the beginning of some architecture changes that will hopefully bring some more stability, speed and transparency to the search process.

- better control to the cache by using combined request-header and content access methods
- refactoring of many classes to comply to this new access method
- make shure that the cache is always written if something was loaded
- some redesign of the process how http response results are feeded into the new indexing queue
- introduction of a cache read policy:
* never use the cache
* use the cache if entry exist
* use the cache if the proxy freshness rule confirmes
* use only the cache and go never online
- added configuration options for the crawl profiles to use the new cache policies. There is not yet a input during crawl start to set the policy but this will be added in another step.
- set the default policies for the existing crawl profiles. If you want them to appear in your default profiles you must delete the crawl profiles database; othervise the policy is 'proxy freshness rule'
- enhanced some cache access methods in such a way that unnecessary retrievals are omitted (i.e. for size computation). That should reduce some IO but also a lot of CPU computation because sizes were computed after decompression of content after retrieval of the content from the disc.

- removed the plasma package. The name of that package came from a very early pre-version of YaCy, even before YaCy was named AnomicHTTPProxy. The Proxy project introduced search for cache contents using class files that had been developed during the plasma project. Information from 2002 about plasma can be found here:
http://web.archive.org/web/20020802110827/http://anomic.de/AnomicPlasma/index.html
We stil have one class that comes mostly unchanged from the plasma project, the Condenser class. But this is now part of the document package and all other classes in the plasma package can be assigned to other packages.
- cleaned up the http package: better structure of that class and clean isolation of server and client classes. The old HTCache becomes part of the client sub-package of http.
- because the plasmaSwitchboard is now part of the search package all servlets had to be touched to declare a different package source.
