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)
dump commands
- adjusted the apicall.sh script to get the downloaded text as output to
stdout which is necessary to parse the content out of it
- added indexdump.sh script which creates a solr dump and prints out the
storage path for the index dump
- added synchronization to the Fulltext class to prevent that data is
stored to a non-existing solr index while this index is disabled during
the storage of the dump
- indexUrlMustMatch and indexUrlMustNotMatch which can be used to select
loaded pages for indexing. Default patterns are in such a way that all
loaded pages are also indexed (as before) but when doing an expert crawl
start, then the user may select only specific urls to be indexed.
- crawlerNoDepthLimitMatch is a new pattern that can be used to remove
the crawl depth limitation. This filter a never-match by default (which
causes that the depth is used) but the user can select paths which will
be loaded completely even if a crawl depth is reached.
- the list of urls is entered in the expert crawl start in a textfield;
the one-line input field was replaced with a text box
- start urls can also be given in one single line where the urls are
separated by a '|'-character
- as an effect, the crawl profile cannot carry a single start url for
identificaton because it is possible to have more. Therefore the url was
removed from the crawl profile
- this affect all servlets which display a crawl profile: removed the
url field from all there servlets
- to work consistently with several start urls and the other crawl
starts which computed crawl start url lists from sitelists or sitemaps,
the crawl start servlet was restructured completely
- new rules for must-match patterns were created to make it possible
that site crawl starts also work with several crawl starts at once
parser/crawler error page whenever a problem with regular expression
occurs.
This makes it easy to correct and enhance the must-match and
must-not-match patterns just by trying out which pattern could be
correct.
- added indexing to Tables columns to support larger bookmark
collections
- added RDF output (HTTP) for public bookmarks at /YMarks.rdf
- YMarkRDF also provides a Jena RDF Model as "internal" API
- various other changes/fixes for YMarks (mainly backend)
- a solr field collection_sxt can be used to store a set of crawl tags
- when this field is activated, a crawl tag can be assigned when crawls
are started
- the content of the collection field can be comma-separated, all of
them are assigned to the documents when they are indexed as result of
such a crawl start
- a search result can be drilled down to a specific collection; this is
currently only available in the solr interface and also in the gsa
interface using the 'site' option
- this adds a mandatory field for gsa queries (the google api demands
that field all the time)
- reduced danger that a non-existing RWI database causes NPEs
- added Solr queries to did-you-mean: this makes it possible that our
did-you-mean algorithm works together with only Solr and without RWIs
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
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)
for production as a replacement of the metadata-db.
This intermediate release 1.041 will switch on the previously optional
solr index and the old metadata-db will still work as it did before.
Solr+metadata are accessed in mixed mode, no migration is done yet.
If this causes not a catastrophe until the end of the weekend, we will
do a YaCy 1.1 main release containing this as default.
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.
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.
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
