24d9db1613 snippet retrieval loading processes may use a smaller minimum load time
value than crawling processes. This speeds up the search result
preparation dramatically.

69e743d9e3 - more abstraction for the RWI index as preparation for solr integration
- added options in search index to switch parts of the index on or off

0cbda0b2b8 - replaced all length() == 0 and size() == 0 with isEmpty()
- replaced some length() > 0 and size() > 0 with !isEmpty() - cannot be
done automatically
- implemented some isEmpty() methods

aef9dd0350 - removed cleaning of blacklist cache on startup
- added cleaning of blacklist cache if cache is modified in interface
- extended cache saving to all cache types
- moved cache location to DATA/LISTS
- fixed static file path which was relative to the application path but
should be relative to data path - which is different in debian and mac
implementations

c3db015410 prevent loading of content from the cache when retrieval with IFFRESH is
used and cache is stale. Should speed up snippet generation when cache
strategy is IFFRESH.

03280fb161 removed segments-concept and the Segments class:
the segments had been there to create a tenant-infrastructure but were
never be used since that was all much too complex. There will be a
replacement using a solr navigation using a segment field in the search
index.

659178942f - Redesigned crawler and parser to accept embedded links from the NOLOAD
queue and not from virtual documents generated by the parser.
- The parser now generates nice description texts for NOLOAD entries
which shall make it possible to find media content using the search
index and not using the media prefetch algorithm during search (which
was costly)
- Removed the media-search prefetch process from image search

ef5192f8c9 using the generic document parser for crawl starts instead of the html
parser. This makes it possible that every type of document can be a
crawl start point, not only text documents or html documents. Testet
this with a pdf document.

e22f8497c9 - tested the ARC methods
- 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)

49e5ca579f added new configuration property "crawler.embedLinksAsDocuments". If this is switched on (this is default now), the all embedded image, audio and video links from all parsed documents are added to the search index as individual document. This will increase the search index size dramatically but will also enable us to create a much faster image, audio and video search. If the flag is switched on, the index entries are also stored to a solr index, if this is also enabled.

c7b95e8c81 *) Invalid crawl profiles (containing invalid mustmatch/mustnotmatch filters) will be moved from active crawls to invalid crawls (new file: DATA/INDEX/freeworld/QUEUES/crawlProfilesInvalid.heap). This file can not be edited yet, but it shoudl be easy to extend the CrawlProfileEditor accordingly.
*) Corrupt crawlProfilesPassive.heap would cause crawlProfilesActive.heap to be deleted. Don't know if this ever happend, but will not happen anymore.
*) Cleaned up a little bit.
*) Added some comments.

0c1b29f3c9 - applied many small performance hacks
- added a memory limitation in the zip parser and the pdf parser
- added a search throttling: if there are too many search queries are still to be computed, then new requests are not accepted for some time. if after a one second still no space is there to perform another search, the search terminates with no results. this case should only happen in case of DoS-like situations and in case of strong load on a peer like if it is integrated in metager.
- added a search cache deletion process that removes search requests in case that throttling happens

4bea3f9714 hack to reduce resource contention caused by massive UTF8 decodings which use java.nio resources:
used a ASCII String <-> byte[] conversion wherever possible. Many Strings in YaCy are hashes which are pure ASCII (base64 hashes).
The new ASCII String <-> byte[] conversion method have less computation overhead than the UTF8 conversion.

4588b5a291 - fixed document number limitation for crawls that restrict the number of documents per domain
- some restructuring of the document counting and logging structures was necessary
- better abstraction of CrawlProfiles

- more refactoring to get the LibraryProvider more clean
- some refactoring of the Condenser class
