YaCy supports now the storage to remote solr indexes.
More federated storage (and search) methods may follow.
The remote index scheme is the same as produced by the SolrCell; see
http://wiki.apache.org/solr/ExtractingRequestHandler
Because this default scheme is used, the default example scheme can be used as solr configuration
This is also the same scheme that solr uses if documents are imported with apache tika.
federated solr storage is switched off by default.
To use this, do the following:
- set federated.service.solr.indexing.enabled = true
- download solr from http://www.apache.org/dyn/closer.cgi/lucene/solr/
- extract the solr (3.1) package, 'cd example' and start solr with 'java -jar start.jar'
- start yacy and then start a crawler. The crawler will fill both, YaCy and solr indexes.
- to check whats in solr after indexing, open http://localhost:8983/solr/admin/
Until now it is not possible to use the solr index to search with YaCy in that solr index.
This functionality is now available for two reasons:
1) to compare the functionality of Solr and YaCy and to compare the search speed
2) to use YaCy as a search appliance for people who need a crawler or other source harvesting methods
that YaCy provides (like dublin core reading, wikimedia dump reading, rss feed reader etc) if people still
want to use solr instead of YaCy.

(directly or indirectly) and it grants a crawl-delay of 0. Then all forced pause mechanisms in YaCy are switched off and the domain is crawled at full speed.
crawl delay values can be assigned to either
- all yacy peers using the user-agent yacybot
- a specific peer with peer name <peer-name>.yacy or
- a specific peer with peer hash <peer-hash>.yacyh

1) if the file is changed for a re-crawl this is not reflected in the steering because it would take the previously uploaded crawl start file
2) browsers do not submit the full path of the selected file even if this path is shown in the input field because of security reasons. There is no work-around or hack to make the submission of the full path possible
- fixed deletion of crawl start point urls in crawl stack and balancer double-check
- fixed a problem with steering self-call (no resolving of localhost)
- added more logging for the crawler to supervise why crawl urls are not taken by the loader
- added a javascript onload-function to select domain restriction in all cases where a crawl is started from a file or from a url
- fixed the restrict-to-domain pattern computation, added a 'www.'-prefix and added this functionality also to a crawl start from file

- some restructuring of the document counting and logging structures was necessary
- better abstraction of CrawlProfiles
- added deletion of logs to the index deletion option (if the index is deleted using the servlets) which is necessary to reset the domain counters for the page limitation
- more refactoring to get the LibraryProvider more clean
- some refactoring of the Condenser class

- yacybot user agent now includes the yacy network name (not the peer name!)
- refactoring and clean-up (mostly turned tab into spaces)

- permanent storage of auto-dom statistics in profile
- storage of profiles in WorkTable data structure
not finished yet. No functional change yet.

- added statistics about database index caches in PerformanceMemory_p.html
- adoped many classes to use the new statistics
- added missing close statements

- crawl lists for each domain now uses a HandleSet which should use less memory than LinkedLists
- but: fill more entries into the domain lists (all available entries)
- fixes to selection criteria (best domain selection)

- added crawling queue sizes to /api/status_p.xml, syntax same as in queues_p.html
- fixed a bug in queue enumeration that caused a out of bounds exception

- enhanced the Balancer performance when building new domain stacks using a new Table buffer
- added the new Table buffer BufferedObjectIndex class
- changed order of access to LURL-read (prefereing segment over Crawl Queues) will reduced blocking time on balancer
- fixed PPM setting in Crawler_p servlet (had doubled values)
- reduced synchronization in IndexCell because it is not necessary: reduced blocking during indexing/merging/dumping
- removed did-you-mean cache in IndexCell because that caused too much overhead and more memory usage but was not very useful. This reduced also deadlocks that could be causes when searched are performed during indexing.

The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

pass value as byte[], not as String. This should cause that less
byte[] <-> String conversions are made during time-critical tasks.
This redesign is not yet complete, more to come ..

- speed enhancements for the cache-only cache policy by using special no-delay rules in the balancer
- fixed some deadlock- and 100% CPU problems in the balancer

- added special rule to balancer to omit forced delays if cache is used exclusively
- extended the htCache size by default to 32GB
