superfluous. The target is to make a solr document as the core of YaCy
documents which would cause that many conversions can be removed. On the
way to this target the Equivalence of URIMetadataRow and URIMetadataNode
had to be removed to expose the usage of the old URIMetadataRow data
structure.
This refactoring already removes unneccessary conversions and should
make memory usage during indexing lower.
which had been then mixed with remote RWIs. Now these Solr documents are
feeded into the result set as they appear during local and remote
search. That makes the search much faster.
URIMetadataNode which creates the opportunity to access Solr objects
directly and use their information richness
- lazy initialization of the URIMetadataNode object - should cause less
computation and memory usage during search.
- removed dead code
MultiProtocolURI during normalform computation because that should
always be done and also be done during initialization of the
MultiProtocolURI Object. The new normalform method takes only one
argument which should be 'true' unless you know exactly what you are
doing.
- added indexing to Tables columns to support larger bookmark
collections
- added RDF output (HTTP) for public bookmarks at /YMarks.rdf

- various other changes/fixes for YMarks (mainly backend)
title_count_i, title_chars_val, title_words_val
description_count_i, description_chars_val, description_words_val
- added many asserts to ensure data type correctness from YaCy to Solr
and vice versa
- made many fixes according to new findings from these asserts (!)
- fixed type definition found by the verifier
- added multivalue-string fields for solr with extension 'sxt'
- added multivalue-integer fields for solr with extension 'val'
- renamed some solr attributes from txt to sxt
- changed solr query line to an explicit AND/OR structure
- added a country code second level domain list to Domains class; with
parser
- added a host string parser to get domain class name, country-code
second-level domain and subdomain out of it
- removed old coordinate attributes

metadata representation from the solr index. This shall replace metadata

- added the Solr-driven metadata into the search index of YaCy which

a rss/opensearch writer and an enhanced solr xml writer.
The enhanced solr writer has less configuration overhead than the
original writer and should by slightly faster. The rss/opensearch writer
is at this time slightly incomplete compared with the already existing
rss search result form YaCy and also snippets are missing at this time.
To test the new interface, open for example:
http://localhost:8090/solr/select?wt=rss&q=olympia
The wt-code for the new result writers are=
wt=rss for opensearch
wt=exml for the enhanced solr xml writer.
Additionally, the SRU search parameters had been added to the solr
interface which can now also be used for a normal solr/xml search.

this case.
- vocabulary annotation is not done any more into the metadata of urldb
- vocabularies are written into the jena triplestore using a rdf
vocabulary
- vocabularies for rdf tripel must be updated; refactoring done
- with the new navigation tags in the triplestore a faster
pre-urldb-lookup is possible: navigation is processed now within the RWI
during pre-ranking retrieval
- added also a Owl vocabulary stub to add the plain-text url to the
triplestore using the owl:sameas predicate

- new limit to use the table copy (instead of flag): 400MB available. If
less is available, then a copy is never used. If more is available, then
it can be used if there is a remaining space of at least 200MB

not equal. It might happen that these data is different because one of
that caches is cleaned after a while or when it is too big. The metadata
is then not cleaned, but now wiped after a checkup process at every
application start. This should cause a bit less memory usage.
- added log warnings in case that search processes run into time-out
situations
- better concurrency for Integer formatter (used a non-synchronized
formatter before)
- bugfix for search termination (a poison pill was missing)
- added timeout parameters for search (again) -> target is, that they
are never reached.
- search request are now made using a map boundary
- search results are only computed for the map boundary
- the number of results is adopted to the results in the visible range
- added a double-buffering for the search result markers
- added a search query option for the search results:
/radius/<lat>/<lon>/<radius>
SeedDB.lookupByName searche for lowercase peerNames, while MapColumnIndex.getIndex uses peername as is in the keyset.
Changed the index init to insert lowercase peer names as key

Hashtable is an obsolete collection v1, now since v2 offers HashMap with same or better
functionality. Please review, almost all code was already moved, so only a few changes. That is not the issue,
but I found notices that some (ugly big) helper classes had to be created in past
to compensate missing Hashtable's functionality. I'd like input if we can remove some of them.

You can toggle between previous (standard) and new (generation) strategy at PerformanceMemory_p.html.
The generation memory strategy is implemented with the objective of running more robust
but with the cost of early stopping some tasks (eg. dht) while running low on memory.
This new strategy does respect the generational way a heap is organized on most used jvms.
These changes run fine on my 3 peers for weeks now, but as I'm human, I may fail.
Please be carefull using generation memory strategy and report errors by naming
OS, jvm and java_args.

- 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

This time it works like this:
- each peer provides its ranking information using the yacy/idx.json servlet
- peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob
- this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable
- I computed new ranking tables as part of the distribition and commit it here also
- the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers
- a recursive block rank refinement is implemented but disabled at this point. it needs more testing
Please play around with the ranking settings and see if this helped to make search results better.
git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7729 6c8d7289-2bf4-0310-a012-ef5d649a1542
This servlet currently only serves for indexes to the web structure hosts. It can be tested by calling
http://localhost:8090/yacy/idx.json?object=host
This yacy protocol servlet is the first one that returns JSON code and that also shows index entries in a readable format. This will make the development of API applications much easier. This is also an example implementation for possible json versions of the other existing YaCy protocol interfaces.
The main purpose of this new feature is to provide a distributed block rank collection feature. Creating a block rank is very difficult if the forward-link data is first collected and then one peer must create a backward-link index. This interface provides already a partial backward index and therefore a collection of all these indexes needs only to be joined which is very easy. The result should be the computation of new block rank tables that all peers can perform.
To reduce load from peers this servlet buffers all data and refreshes it only once in 12 hours. This very slow update cycle is needed because the interface will be called round-robin from all peers once after start-up.
