- 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
or will be superfluous or subject of complete redesign after the
migration to solr. Removing these things now will make the transition to
solr more simple.
