- when using a site operator search for a domain where the domain has a
www prefix, also the domain without the www is enclosed
- when using a site operator search for a domain where the domain has no
www prefix, also the domain with the www in enclosed
- in the host navigator, all domains with and without a www prefix are
accumulated. That means that the host navigator does never show a host
with a www prefix.
This should prevent usage mistakes of the site operator.
introduce a copy-field for the author field to be copied to a string
field. This field is then used to generate facets. Without this field,
the facet would consist only of the words of the author names, not of
the full author string.
need regular expressions as search attributes. They had now been removed
from the advanced search page while they are still created internally.
The filter is then expressed against solr as regular expression filter
query. If the expression points out a selection of an specific protocol,
host or filetype this is then translated into a facetted query.
added solr highlighting / YaCy snippets to YaCy search results
- facets are now much more complete
- facets are computed and searched much faster
- snippet computation is done by solr if solr knows the snippet
caused by a JRE bug, the PixelGrabber had to be circumvented using an
own frame buffer which can be read without a PixelGrabber. This resulted
in ultra-fast and much less memory-consuming transformation. YaCy images
are now generated really fast!
- replaced the dot in the NetworkGraph with arrows
- enhanced the image drawing speed using pre-computed color values
- added more attention for OOM cases during very large image painting
- multiple hosts can be listed (comma-separated) as host argument
- new 'bf'-attribut (branch factor): the maximum number of edges per
node
- the bf-value is computed automatically
- ordering of nodes when the graphic is drawed: mostly the drawing ends
with an limitation eg. number of nodes. When this happens, it should be
ensured that more 'interesting' nodes are painted in advance. This is
now done by sorting all nodes by the number of links they have in de
distant sub-graph.
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
create an document entry. This makes remote search much slower.
- removed synchronization of add method if ip_s is activated to prevent
that a user configuration causes bad behavior. The disadvantage of that
is, that a index dump can cause data loss if an indexing is running
during index dump
- catched more exceptions and more NPE
- better abstraction in MirrorSolrConnector
- slight performance enhancement when only the index count is requested
(rows=0 is sufficient to get a total count)
Node to Row objects
- removed peerDeparture in solr remote search in case that peer does not
answer (this may be normal because it is allowed to switch this off)
- when doing a remote search, node peers are selected for solr queries
- the solr query is done concurrently to the standard YaCy rwi search
- the solr search result is feeded into the same data structure that
prepares the rwi search result
- the same remote seach that is done to several outside peers is done to
the local solr index
- the search process works now also without any 'old' RWI data using
solr
attached, the metadata is not written to the metadata-db, even if it is
enabled but instead to solr. This prevents that metadata is written in
two store systems at the same time. It is also the next step to migrate
the current metadata-db to solr.
metadata representation from the solr index. This shall replace metadata
from the built-in database in the future.
- added the Solr-driven metadata into the search index of YaCy which
makes it now possible to run YaCy without the old metadata index. This
is a major stept forward to a full migration to Solr.
writings to the Metadata-DB are now also done to solr. This includes
metadata transfer during search and rwi transfer.
The new/added solr fields are:
## time when resource was loaded
load_date_dt
## date until resource shall be considered as fresh
fresh_date_dt
## id of the host, a 6-byte hash that is part of the document id
host_id_s
## ids of referrer to this document
referrer_id_ss
## the md5 of the raw source
md5_s
## the name of the publisher of the document
publisher_t
## the language used in the document; starts with primary language
language_ss
## an external ranking value
ranking_i
## the size of the raw source
size_i
## number of links to audio resources
audiolinkscount_i
## number of links to video resources
videolinkscount_i
## number of links to application resources
applinkscount_i
- 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.
only links where the content can be parsed. All non-parseable links are
placed into the noload queue. The search process must therefore be able
to filter out non-text search results.
- This fixes the problem that image search results appeared in the text
search.
- The interactive search can retrieve now ALL types of links
- The p2p interface is now extended to retrieve only certain types of
links (text, image, video, apps)
- The search process has an extension to filter the right document type
according to the search query
during receiving of DHT submissions and when answering remote search
requests. Both events together may have caused IO-deadlocking and this
commit shall fix that.
parser. This makes it possible that every type of document can be a
crawl start point, not only text documents or html documents. Testet
this with a pdf document.
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.

better-ranked search results. without that pauses the result page will
only contain links from the peer that answers first which is not a good
average picture of all the peers that provided results
- release number
- date
- svn number
additionally there is a new option to remove the svn number completely
