Here a new concept called 'search heuristics' is introduced. A heuristic is a kind of 'shortcut' to good results in IT, here for good search results. In this case it will be used to get a very transparent way to compare what YaCy is able to produce as search result and what g**gle produces as search result. Here is what your can do now:
- add the phrase 'heuristic:scroogle' to your search query, like 'oil spill heuristic:scroogle' and then a call to scroogle is made to get anonymous search results from g**gle.
- these results are _not_ taken as meta-search results, but are used to instantly feed a crawling and indexing process. This happens very fast, here 20 results from scroogle are taken and loaded all simultanously, parsed and indexed immediately and from the results of the parsed content the search result is feeded, along to the normal p2p search
- when new results from that heuristic (more to come) get part of the search results, then it is verified if such results are redundant to existing (they had been part of the normal YaCy search result anyway) or if they had been completely new to YaCy.
- in the search results the new search results from heuristics are marked with a 'H ++' and search results from heuristics that had been already found by YaCy are marked with a 'H ='. That means:
- you can now see YaCy and Scroogle search results in one result page but you also see that you would not have 'missed' the g**gle results when you would only have used YaCy.
- to make it short: YaCy now subsumes g**gle results. If you use only YaCy, you miss nothing.
to come: a configuration page that let you configure the usage of heuristics and get this feature by default.

- used that to display two layers on map: cities and search result locations
- added many marker grafics for the display of the markers on the map
- some refactoring of the yacy news code plus bugfixes for latest move from Tree to Table data structure

- added 'select all' feature in Tables_p
- enhanced ViewFile.html: has now an input field to load arbitrary resources from the web and analyze them (!!!)
- included the ViewFile servlet into the Index Administration menu
- show in ViewFile if ressource is in url-db and/or in Web cache
- bugfixes to BEncodedHeap and Tables management

- start again a previously started crawl
- submit settings (again). This option will be used to transmit
all settings of one peer to another peer if the remote-peer
steering function is ready
This steering framework will also be used for a 'schedule-everything'
which will also include a new scheduler for crawling.

all operations on YaCy in a database that should make it possible
1) to re-create a setting on fresh peers
2) to transmit a setting from one peer to another
3) to re-create crawl starts after a complete deletion of the index
This functionality will also support
4) scheduled re-crawls (new implementation)
To implement this, a new database structure has been crated that stores maps into blob heaps. to encode maps the b-encoding technique was used (this is the same encoding that torrent files use)
- added a b-encoder
- enhanced the b-decoder
- added a b-encoded map heap data structure
- added a table organisation based on b-encoded heaps
- added a servlet to maintain such tables (see Tables_p.html)
- integrated the servlet into the Advanced Settings menu
- added an api recording based on the new tables

this is a work-around for the problem that the search widget
does not load a second page if the first page did not fill up
the window with enough lines such that a scrollbar ist visible.
Because the scrollbar triggers loading of following pages, this
must be enforced with the trick that more result lines must be
shown after the first search.

this was done because that servlet may be used for wget/cronjob
triggered crawl starts and it appears to be confusing that the
name of the crawl start servlet looks like a pure monitoring tool.

- moved all index generation servlets to it's own main menu item, including proxy indexing
- removed external index import because this operation is not recommended any more. Joining an index can simply be done by moving the index files from one peer to the other peer; they will be merged automatically
- fix to prevent endless loops when disconnecting http sessions
- fix to prevent application of bad blacklist entries that can cause a 'Dangling meta character' exception

- some refactoring in search process
- fixed image search for json and rss output
- search navigation on bottom of search result page in cases where there are more than 6 results on page
- fixes for number of displayed documents
- disabled pseudostemming

- added many stack trace outputs for exceptions in crawl profile handler to find the 'missing profile handle' bug
- catched one more timeout exception in httpd file loader

- extended the OAI-PMH test applet and integrated it into the menu. Does still not import OAI-PMH records, but shows that it is able to read and parse this data
- some redesign in ZURL storage: refactoring of access methods, better concurrency, less synchronization
- added a limitation to the LURL metadata database table cache to 20 million entries: this cache was until now not limited and only limited by the available RAM which may have caused a memory-leak-like behavior.

- search result headline font is slightly larger and has an underline (like g**gle)
- no dashed line between results in grey style
- no search results with menu on left side by default (but is still possible)

- 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.

Future versions of YaCy will have different file structures than given here, because of the new index segment concept, where each peer may have several indexes (called segments) for each network definition. A copy from one peer to another will then create a new index segment.
