switch between p2p search and the 'stealth mode' which is simply a
non-p2p search within the p2p network. The functionality was there all
the time, but the switch to this was not very visible.
4.0.0 there is a new softcommit feature which implements a
near-real-time (NRT) search option. The softcommit does not do IO and
does not cause performance issues.
YaCy has now an extension in its solr connectors to use the softcommit
feature. The softcommit call now replaces all places where a hard commit
was used. Furthermore the commit strategy in when doing a search from
the web interface was changed (it's done every time before a search is
done).
The softcommit feature was implemented because it was needed for the
following changes (customer demands), which is also included in this
git commit:
- added a feature to identify all documents which have unique titles
and/or unique descriptions. These unique flags are disabled by default.
- added also a feature to set a flag when the url from a canonical tag
is equal to the document url. This is also disabled by default.
To support the new softcommit strategy, the commitWithinMs option was
set to -1 do disable automatic commit based on document insert times. If
documents are inserted permanently then also a commit would happen
permanently whenever the commitWithinMs time is reached. This would
conflict with the regular autocommit of 10 minutes and the new
softcommit strategy.
This uses an enhanced version of the Nutch/Solr TextProfileSignatue.
As a result, a signature of the document is written to the solr search
index. Additionally for each time when a signature is written, it is
checked if the singature exists already in the index. If the signature
does not exist, the document is marked as unique. The unique attribute
can now be used to sort document lists and bring duplicates to the end
of a result list.
To enable this, a large portion of the search api to Solr had to be
changed. This affected mainly caching of 'exists' searches to enhance
the check for existing signatures and do this without actually doing a
solr query.
Because here the first time a long number is used as value in the Solr
store, also the value naming in the YaCySchema had to be adopted and
normalized. This caused that many files had to be changed.
need regular expressions as search attributes. They had now been removed
from the advanced search page while they are still created internally.
The filter is then expressed against solr as regular expression filter
query. If the expression points out a selection of an specific protocol,
host or filetype this is then translated into a facetted query.
- removed strict authentication (if password is empty; this was buggy and not useful; can be switched on if necessary globally and not for each interface method)
- increased speed of CrawlResults page (no dns lookup any more)
- increased speed of favicon display (removed dns lookup)

- removed configuration button for 'search only for admin' from index.html and added this to ConfigPortal
- added configuration of link verification options (iffresh, cacheonly, nocache, ifexist) to ConfigPortal
- added configuration of navigation options to ConfigPortal
- added an option to switch off automatic index cleaning in case that a link verification method fails

instead, a setting at ConfigPortal.html can be made to define if the topmenu shall be shown at these pages or if there is no naviagtion at all.

"Default index.html Page (by forwarder)" in /ConfigPortal.html
The purpose is to forward to /yacyinteractive.html for the 27C3 FTP search plattform

- move the header framework classes to cora
- move the ARC caching classes to cora
- refactoring of code to call these classes from cora

- 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.

- The indexing queue was a historic data structure that was introduced at the very beginning at the project as a part of the switchboard organisation object structure. Without the indexing queue the switchboard queue becomes also superfluous. It has been removed as well.
- Removing the switchboard queue requires that all servlets are called without a opaque generic ('<?>'). That caused that all serlets had to be modified.
- Many servlets displayed the indexing queue or the size of that queue. In the past months the indexer was so fast that mostly the indexing queue appeared empty, so there was no use of it any more. Because the queue has been removed, the display in the servlets had also to be removed.
- The surrogate work task had been a part of the indexing queue control structure. Without the indexing queue the surrogates needed its own task management. That has been integrated here.
- Because the indexing queue had a special queue entry object and properties attached to this object, the propterties had to be moved to the queue entry object which is part of the new indexing queue withing the blocking queue, the Response Object. That object has now also the new properties of the removed indexing queue entry object.

- added a configuration option to set the pop up page in Config Appearance
- added a minimized header option to yacyinteractive
- fixed a bug in yacysearch: default values when no query is done

- removed distinction between header file types for http and ftp; ftp is simulated by using http properties
- removed all old resourceInfo classes that handled this distinction
- introduced a new distinction between http request and http response objects
- unified new response objects with two other object types that had been introduced elsewhere
- changed all servlet call methods to use the new http request header object type
- divided static object keys for http header properties into request and response types
- refactoring here and there (a large number of type changes and many methods merged/moved)

- moved constants from plasmaSwitchboard to own class (all 232 ;)
- moved remoteProxy-Methods to httpRemoteProxyConfig, better names
- removed some unnecessary code (else-statements)
* formatting (correct indentation)
* minor bugfixes (due to findbugs.sf.net)
* hopefully fixed "missing quote" (announcing StringParts as UTF-8)
