and replaced old fist hash computation by new method that tries to find a gap in the current dht
to do this, it is necessary that the network bootstraping is done before the own hash is computed
this made further redesigns in peer initialization order necessary

- added a file size limitation, that disallows parsing of large documents during (offline-) remote search
- added profiling information to search result computation, visible at search access tracker. this info shows used time for URL fetch and snippet computation

- fixed search tipps (topwords, now appearing at the bottom of the page)
- added search consequences execution (deletion of bad referenced some time after the search happened)
- added some formatting at network table

search profiling showed, that a major amount of time is wasted by computing url hashes. The computation does an intranet-check, which needs a DNS lookup. This caused that each urlhash computation needed 100-200 milliseconds, which caused remote searches to delay at least 1 second more that necessary. The solution to this problem is to attach a URL hash to the URL data structure, because that means that the url hash value can be filled after retrieval of the URL from the database. The redesign of the url/urlhash management caused a major redesign of many parts of the software. Since some parts had been decided to be given up they had been removed during this change to avoid unnecessary maintenance of unused code.

- snippets are not fetched by browser using ajax, they are now fetched internally
- YaCy-internat threads control existence of snippets and sort out bad results
- search results are prepared using SSI includes
- the search result page is visible right after the search request, the results drop in when they are detected
- no more time-out strategy during search processes, results are shifted within queues when they arrive from remote peers
- added result page switching! after the first 10 results, the next page can be retrieved
- number of remote results is updated online on the result page as they drop in
- removed old snippet servelet (which had been also a security leak btw)
- media search is broken now, will be redesigned and fixed in another step

it is necessary for the new search process that will do automatic re-searches
a positive effect is, that when a re-search is done it can be monitored how many
results had been contributed from other peers. The message for this contribution
was moved from the end of the result page to the top.
* enhanced re-search time when a global search was done an the local index has
already a great number of results for this word
* re-organised presearch computation; must be further enhanced

- re-designed remote request result processing
- re-designed local result accumulation, will be further enhanced with snippet fetcher
- removed search process handling in switchboad
- made snippet class static (there is no need for multiple snippet objects)
- removed some redundant tasks in server-side search process, should be a little bit faster now

- the network configuration page shows a new option: robinson clusters
- when a global search is made, all robinson peers are excluded, but:
- robinson peers/clusters that provide peer tags and where search words match
such tags, they are included in global search. Therefore, robinson peers/clusters
support the global yacy network with their indexes, without doin DHT-exchange

- exclusion on index-level (not only from search snippets)
- exclusion hand-over at remote search protocol

- basic protection against start-up problems when database files are corrupted
- auto-delete of not-critical databases during startup when load error occurs
- on-the-fly reset option for all database tables
- automatic on-the-fly reset for seed tables during enumeration exceptions

- redesign of data storage in plasmaSearchRankingProfile
- profiles are extended by new ranking parameters
- new RWI ranking parameters are considered during ranking
- appearance attributes (i.e. emphasised text) is now considered
- faster ranking
- some attributes that had been checked during post-ranking can now be
checked during pre-ranking phase
- removed old ranking parameter on index.html page (will be replaced by profiles in the future)
- ranking can now consider appearances of media content
- snippet-loading for media types now work correctly (fetches only from the wanted media)
- ranking-profiles can be handed over the remote peers and apply there also
- re-search of same query with different domain now also re-triggers remote search

- added an assortment importer. the old database structures can
be imported with
java -classpath classes yacy -migrateassortments
- modified wordmigration. The indexes from WORDS are now imported
to the collection database. The call is
java -classpath classes yacy -migratewords
(as it was)

to search procedure. This function can currently not used through the
search interface, but only through remote search.
added accumulation of search attributes to enable the audio, video,
image and application selection.
fixed a problem with external URL representation generation

post-parameter url to submit an url directly
- fixed some bugs in text parser (not all parts had been analysed)
- fixed a bug in remote search interface (could not handle constraints)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3001 6c8d7289-2bf4-0310-a012-ef5d649a1542
Such constraints may formulate specific restrictions to web searches
This is implemented by scraping information for constraints from a web
page during parsing, and storing flags to the pages within the web index.
In this first step, only information for index pages ("index of", directory listings)
are scraped and stored in flags
- added new flag class kelondroBitfield
- added scraper method in condenser
- added bitfield structure for all scrape types (see also condenser)
- added bitfield structure for appearance locations (see RWIEntry)
- added handover protocol for remote search and index distribution
- extended kelondroColumn class to hold bitfield types
- added another search attribute on search page (index.html)
- extended search-filter to enable filtering of non-matching constraints
- set all new database types to be default
- refactoring: moved word hash generation to condenser class

- moved all url and index(RWI) entries to index package
- better naming to distinguish RWI entries and URL entries

- added test migration method to migrate the old LURL to a new LURL
the new LURL will be splitted into different tables for each month
this solves several problems:
- the biggest table in YaCy is splitted in different parts and can
also be managed in filesystems that are limited to 2GB
- the oldest entries can easily be identified, used for re-crawl und
deleted
- The complete database can be limited to a specific size (as wanted many times)

- removed settings that are in Basic Settings
- joined pages that belong together
- moved include pages from yacy/ to /
