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
API recording for this method so it can be repeated automatically. The
index dump generation is now also available for API recording. Added
some synchronization in backend which was necessary for this.
id to be tested, but with a collection of ids. This will cause only a
single call to solr instead of many. The result is a much better
performace when testing the existence of many urls. The effect should
cause very much less IO during index transmission, both on sender and
receiver side.
process counter if an blocking thread dies. Added also a new column in
PerformanceConcurrency_p servlet to show the actual number of concurrent
processes.
This will enable https-access to YaCy, but this feature is disabled by
default using the new server.https=false attribute. This has two
purposes:
- make it easier for everyone to use https (just set server.https=true)
- provide the basis for secure yacy-to-yacy communication in the future
appeared after the declaration of robots allow/deny for the crawler
because the sitemap parser terminated after the allow/deny rules had
been found. Now the parser reads the robots.txt until the end to
discover also sitemap rules at the end of the file.
Because the index size is now provided by solr, and the only way to do
that is a match for [* TO *], a size computation is quite complex and
time-consuming. Therefore this patch prevents that the method is called
at all and if necessary puts a DOS-preventing barrier in front of it.
- on-demand collection-list generation for collection-based deletions
instead of a default collection-list presentation (this makes calling
the interface much faster since the computation of collections lists for
large indexes may take some seconds)
- added the field in crawl profile
- adopted logging end error management
- adopted duplicate document detection
- added a new rule to the indexing process to reject non-matching
content
- full redesign of the expert crawl start servlet
The new filter field can now be seen in /CrawlStartExpert_p.html at
Section "Document Filter", subsection item "Filter on Content of
Document"
adjusted to smaller and 1-core devices.
- the workflow processor now starts no process at all. these are started
as soon as parser/condenser/indexing queues are filled.
- better abstraction
used to select between different collections as defined during a crawl
start with the 'collection' attribute. This actually implements the
ability to prepare search tenants which restrict their search results to
a specific collection. The main use for this is to provide tenants to
the yaml4 interface (at this time).
holds the number of documents for the host where the document is hosted.
This is necessary for ranking and the norming of references per local
host in the ranking computation.
search interfaces if no other ranking attributes are given
- using the YaCy ranking in the GSA interface only if there was not
given a GSA-style sort attribute
- to avoid confusion about correct ranking attributes, only the default
'0'-ranking profile is used and not scenario-adopted (site, date)
because that should be configurable in the web interface before it is
used actually for ranking.
- memory allocation problem in RowCollection: if memory is too low, do
not to try to increase by 1 because this leads to very long execution
time and at the end to the same OOM as if we allocate the memory at the
moment we need it even if the resource observer states that this memory
is not there. To compensate this, the increase size is reduced.
- no document search this time
- adjusted banner and network to not show 'WORDS' but DHT Chunks. This
is to avoid confusion for robinson peers which do not create Word
Entries
- an existing ranking servlet for solr was extended. It is now possible
to set boost values for fields, boost functions and boost queries.
- The ranking can have different instances, but currently only the first
one is used
- added an abstraction layer for fields which can be used for search and
those fields can be edited in the solr ranking configruation
- the ranking value from solr within the field score is used to combine
remote search requests, which all are created using the same locally
defined boost values
- reduced the number of fields which are used for search (makes it
faster)
- replaced some text fields by string fields (makes indexing faster)
- removed classes which had no use
- made a large number of experiments for a better ranking and created a
temporary setting which prefers hits inside titles
- adjusted also the RWI-based ranking computation to 'prefer title'
- made special cases like for portal search where no post-processing and
post-ranking is wanted: this keeps the original ranking order as done by
Solr
- fixed many bugs with old settings for ranking
- removed unused solr access classes
- made snippet generation for documents aus YaCy RWI/DHT concurrent (as
it was before the search process removation)
- reduced the number of remote results in settings file because the
processing of such mass documents add is too CPU-intensive (in Solr)
