- 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

- for each crawl start, there is now a flag for text and media
- the localCrawl flag is superfluous
- added new crawl profiles
- if an image search is done, only media links are crawled for the snippets

- added self-healing to database in case that wrong free-pointers exist
- added presentation of media links in snippets (does not yet work correctly)
- code cleanup

- removed 'deleteComplete' flag; this was used especially for WORDS indexes
- shifted methods from plasmaSwitchboard to plasmaWordIndex
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3051 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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

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

- the test phase of the new collection data structure is finished
- test data that had been generated is void. There will be no migration
- the new collection files are located in DATA/INDEX/PUBLIC/TEXT/RICOLLECTION
- the index dump is void. There will be no migration
- the new index dump is in DATA/INDEX/PUBLIC/TEXT/RICACHE

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

- bugfix for performaceMemory
- refactoring of index ram cache: renamed indexRAMCacheRI to indexRAMRI, to make space for a cached indexRI, which should be named indexRAMCacheRI
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2925 6c8d7289-2bf4-0310-a012-ef5d649a1542
- enhanced local domain detection
- bugfixing for memory assignment in kelondroFlexSplit
- automatic memory assignment to caches according to available RAM
- bugfixes for details during search process
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2924 6c8d7289-2bf4-0310-a012-ef5d649a1542
- generalized object caching and added new object caching class
- added object caching wherever kelondroTree was used
- added object caching also to usage of kelondroFlex
- added object buffering (a write cache) to NURLs
- added many assert statements; fixed bugs here and there
- added missing close methods to latest added classes
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2858 6c8d7289-2bf4-0310-a012-ef5d649a1542
- 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)

- more synchronization
- bugfix for remove in collections
- bugfix in kelondroFlex (wrong exception condition!)
- options to use RAM, FLEX and TREE tables for Crawl URL stacker
- default for Crawl URL stacker is now FLEX (!)
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2746 6c8d7289-2bf4-0310-a012-ef5d649a1542
- snippets will generate an entry in responseHeader.db
- there is now another default profile for snippet loading
- pages from snippet-loading will be indexed, indexing depth = 0
- better organization of default profiles
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@2733 6c8d7289-2bf4-0310-a012-ef5d649a1542
The bugfix includes a migration function which starts automatically
after startup of yacy.
This applies only to you, if you are using the new collection index.

- method loadResourceContent defined as deprecated.
Please do not use this function to avoid OutOfMemory Exceptions
when loading large files
- new function getResourceContentStream to get an inputstream of a cache file
- new function getResourceContentLength to get the size of a cached file
*) httpc.java:
- Bugfix: resource content was loaded into memory even if this was not requested
*) Crawler:
- new option to hold loaded resource content in memory
- adding option to use the worker class without the worker pool
(needed by the snippet fetcher)
*) plasmaSnippetCache
- snippet loader does not use a crawl-worker from pool but uses
a newly created instance to avoid blocking by normal crawling
activity.
- now operates on streams instead of byte arrays to avoid OutOfMemory
Exceptions when operating on large files
- snippet loader now forces the crawl-worker to keep the loaded
resource in memory to avoid IO
*) plasmaCondenser: adding new function getWords that can directly operate on input streams
*) Parsers
- keep resource in memory whenever possible (to avoid IO)
- when parsing from stream the content length must be passed to the parser function now.
this length value is needed by the parsers to decide if the parsed resource content is to large
to hold it in memory and must be stored to file
- AbstractParser.java: new function to pass the contentLength of a resource to the parsers
