by checking vocabulary tags also for rwi results (currently a filter is applied to the solr query)
TODO: as vocabularies are only locally valid, auto-switch to Searchdom.LOCAL could be considered.
because it's normal that a boolean value is missing in the post argument
if a checkbox is not selected.
Added also some style enhancements to IndexFederated, removed the Solr
attachment manual and replaced it with a link to the wiki which explains
this in more detail.
note: stream.close is done by caller (Textparser.parseSource)
- removed unnecessary reset in AugmentParser
- added stream.mark in tdfatripleimpl. to make stream.reset work here

of the lazy instantiation rule this value was not actually written, but
if lazy instantiation is switched on, then this causes that all crawl
starts delete all crawl-start-hosts completely because this looks for
filled error reasons.

- remove redundant file extension registration
- Rewrote usage of HashMap/Map to concurrent versions (to avoid a
CME=ConcurrentModificationException)
- Rewrote ConnectionInfo (as an example) to use a synchronized iterator
instead of synchronizing an
already synced HashSet (see Collections call)
- This avoids catching CMEs again
- Commented out noisy ConcurrentLog.logException() call

jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger
- textarea input field can now be used to paste in a large list of hosts
- /31er subnet is possible (only one host)
- auto-detect subdomains for ftp and www subdomains
without the file extension. This part of the file path is removed from
the multi-field url_paths_sxt, which has now not the file name as last
part of the path list.
The same applies to the new fields source_file_name_s and
target_file_name_s in the webgraph schema.

superfluous. The citation of referrer in the host browser is possible
without them. Therefore now the host browser does not only show
internal, but also external referrer to each link.
explored for citations within other documents. A click on the
'Citations' link shows an analysis with all text lines in the document
each with a complete list of documents which contain the same line. A
second section shows the linking documents in ascending order of number
of citations from the original document. Because documents from
different hosts are most interesting here, they are listed at the top of
the page as possible 'copypasta' source.
yacy will load linked web pages from search results until the total
number of web pages reaches 15000. This shall give fresh peers a 'boost'
to get faster a personalized search index.
texts, separated by sentences. Then, these sentences can be used to
search again in the index for the same sentence. This can be used to
provide a tool for plagiarism-search. (not finished yet).
Try the following:
http://localhost:8090/solr/select?q=text_t:flut&grep=wasser&defType=edismax&start=0&rows=3&core=collection1&wt=grephtml
.. to search for 'flut' and show only sentences in the result documents
which contain the word 'wasser'.
Consider this like using a grep-tool on documents: you select the
documents by a search query and you grep sentences inside the found
documents with the 'grep' attribute.
output writer. This made the creation of a html result writer necessary
which is included in this commit. The yacydoc servlet was used to
present all metadata to a document, but the solr interface can serve for
this purpose in a much better way. All usages (instead one) of yacydoc
were replaced by a solr call. This affects also the 'metadata' link
attached to search results.
function. This replaces the previous formula, which was bad. Before you
update to this version, please check if you changed the ranking function
yourself before, since it will be overwritten.
While the values for the reference evaluation are computed, also a
backlink-structure can be discovered and written to the index as well.
The host browser has been extended to show such backlinks to each
presented links. The host browser therefore can now show an information
where an document is linked. The new citation reference is computed as
likelyhood for a random click path with recursive usage of previously
computed likelyhood. This process is repeated until the likelyhood
converges to a specific number. This number is then normalized to a
ranking value CRn, 0<=CRn<=1. The value CRn can therefore be used to
rank popularity within intra-domain link structures.

signal in case that a cleanup process wants to remove the search
process. Added also a new cleanup process which can reduce the number of
stored searches to a specific number which can be higher or lower
according to the remaining RAM. The cleanup process is called every time
a search ist started.
soft commits, reduced caching size of search events, ensured that solr
results are processed before connection is closed to keep that stuff not
too long in RAM
