- by default, a (empty) solr storage instance is created at
SEGMENTS/solr_36
- the index is written if in /IndexFederated_p.html the flag "embedded
solr search index" is switched on
- a standard solr query interface is available now with a new servlet at
http://127.0.0.1:8090/solr/select
To test this, do the following:
- switch to webportal mode
- switch on the feature as described
- do a crawl. this fills the solr index. The normal YaCy search will NOT
work now!
- do a solr query, like:
http://127.0.0.1:8090/solr/select?q=*:*
http://127.0.0.1:8090/solr/select?q=text_t:Help
play with different search fields as you can see in
/IndexFederated_p.html
You can use the standard solr query attributes as described in
http://wiki.apache.org/solr/SearchHandler
the segments had been there to create a tenant-infrastructure but were
never be used since that was all much too complex. There will be a
replacement using a solr navigation using a segment field in the search
index.
0-values and no empty strings are written). This may save a lot of
memory (in ram and on disc) if excessive 0-values or empty strings
appear)
- do not allow default boolean values for checkboxes because that does
not make sense: browsers may omit the checkbox attribute name if the box
is not checked. A default value 'true' would not comply with the
semantic of the browsers response.
- add a checkbox in IndexFederated_p for the lazy initialization of solr
fields.
- 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
- flush caches more often: flush the Digest cache
- 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>
- Changing the format of YaCy's solr.key.list while maintainig backward compatibility
Federated index config screens adjusted accordingly
- modified the Solr update request to use a 3 min Solr autocommit intervall
queue and not from virtual documents generated by the parser.
- The parser now generates nice description texts for NOLOAD entries
which shall make it possible to find media content using the search
index and not using the media prefetch algorithm during search (which
was costly)
- Removed the media-search prefetch process from image search
- a new database for url reference data ('seen links')
- a new database extending the references to the full url metadata
attributes set which shall replace the old metadata database if it is
finished
- migration help classes stub to use old and new metadata databases
simultanously
the links between all pages are now stored. The same index structure as
used for the word index is used to make a reverse link index.
The new file(s) in SEGMENT/default/citation.index.*.blob store the
citation index. This will be used to create much more detailed link
structures for the YaCy apis and to create a better ranking. A ranking
using the citation.index should provide better results especially for
portal indexes and initranets.
