b77b8cac0c - enhanced html parser: recognized much more details in the content
- added more properties to solr index
- refactoring
- more constants in switchboard
- fix for some NPEs
- recognition of more images
- removed synchronization in HandleMap (obviously not necessary?)
- added a nolocal configuration to remove excessive dns lookup (works only on allip - default off). Indexes produced with this setting are all flagged with 'local' and are (on purpose) not usable for freeworld because they will be rejected as beeing local.

3d5104d357 - fixed a bug in crawl start with file name (npe in new url)
- added deletion of solr index in IndexControlRWIs
- added asynchronous adding of large url lists (happens when crawls are startet with file)
- fixed npe in Image display
- replaced language warning with fine logging
- added a domain name cache in Domains that helps to speed up the isLocal property (less DNS lookups)
- added a new storage class for this new cache: KeyList. The domain key list is stored in DATA/WORK/globalhosts.list
- added concurrent solr updates and chunked transfers (50 documents until a commit is done) for high-speed feeding (> 40000 ppm)
- fixed a bug in content scraper that chopped off large parts of crawl lists (using crawl start from file)

78d4c45d09 enhancement during search process: fast fail of search in case that all index feeder have terminated.
This change should affect filtering and navigators and should cause that search navigation gets faster

cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.

5892fff51f introduction of dht-burst modes: this can expand the number of target peers in some cases where a better heuristic is needed. The problematic cases are either when a muti-word search is made (still a hard case for our term-oriented DHT) or when a network operator wants that all robinson peers are asked. We therefore introduced two new network steering values that switch on more peers during the peer selection. Because the number of peers can now be very large, the number of maximum httpc connections was also increased.
Please see new coments in yacy.network.freeworld.unit for details of the new DHT selection methods.
The number of maximum peers is now not fixed to a specific number but may increase with
- the partition exponent
- the number of redundant peers
- the robinson burst percentage
- the multiword burst percentage
The maximum can then be the number of senior peers (all visible peers).

0010cd9db1 Support for indexing of RSS feeds!
- added a scanning in html parser for rss feeds
- storage of rss feed addresses, can be viewed with http://localhost:8080/Tables_p.html?table=rss
- rss items retrieved by http://localhost:8080/Load_RSS_p.html (in Index Creation menu) can be selected and indexed
- a rss feed retrieved in http://localhost:8080/Load_RSS_p.html can now be fully indexed
- indexing of rss feeds can be placed in scheduler

b6fb239e74 redesign of parser interface:
some file types are containers for several files. These containers had been parsed in such a way that the set of resulting parsed content was merged into one single document before parsing. Using this parser infrastructure it is not possible to parse document containers that contain individual files. An example is a rss file where the rss messages can be treated as individual documents with their own url reference. Another example is a surrogate file which was treated with a special operation outside of the parser infrastructure.
This commit introduces a redesigned parser interface and a new abstract parser implementation. The new parser interface has now only one entry point and returns always a set of parsed documents. In case of single documents the parser method returns a set of one documents.
To be compliant with the new interface, the zip and tar parser had been also completely redesigned. All parsers are now much more simple and cleaner in its structure. The switchboard operations had been extended to operate with sets of parsed files, not single parsed files.
additionally, parsing of jar manifest files had been added.

3a9dc52ac2 added a fascinating new way to search _and_ start a web crawl at the same time:
implemented a hint from dulcedo "use site: - operator as crawl start point".
YaCy already was able to search using a site-constraint. This function is now extended with a instant crawling feature.
When you now use the site-operator, then the landing page of the site iand every page that is linked from this page are loaded, indexed and selected for the search result within that search request. When the remote server responds quickly enough, then this process can result in search results during the normal search result preparation .. just in some seconds.

7bcfa033c9 more abstraction of the htcache when using the LoaderDispatcher:
a cache access shall not made directly to the cache any more, all loading attempts shall use the LoaderDispatcher.
To control the usage of the cache, a enum instance from CrawlProfile.CacheStrategy shall be used.
Some direct loading methods without the usage of a cache strategy have been removed. This affects also the verify-option
of the yacysearch servlet. If there is a 'verify=false' now after this commit this does not necessarily mean that no snippets
are generated. Instead, all snippets that can be retrieved using the cache only are presented. This still means that the search hit was not verified because the snippet was generated using the cache. If a cache-based generation of snippets is not possible, then the verify=false causes that the link is not rejected.

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
