Main Release 1.6

Release 1.5

This is the YaCy main release 1.4.

This release includes mainly a deeper Solr integration, much more Solr
fields are filled, Solr has now mutli-core capabilities and a second
core with a webgraph was added (but deactivated for further testing).
The opensearch result writer of the integrated solr has now all the
feateures as the original opensearch result servlet of YaCy had, and the
file search interface "yacyinteractive" now uses this new result writer
instead the old one. The search of that interface is now much, much
faster. The default search functionality has undergone a full re-design
and a lot of testing was done to fix problems with the to-solr
migration. The normal search is now very fast, in portal mode and even
in p2p mode. The ranking was strongly enhanced, there is now a support
for flexible field boosts, boost functions and boost queries. All these
ranking functions had been made editable and there is a new
configuration sevlet for this. Furthermore, there are several ranking
schemas predefined, one for default internet search, one for
sort-by-date and one for intranet search requests, which is triggered
automatically if a site-operator is used. Intranet search ranking rates
deep links higher than shallow which returns more specific document
types. Remote searches are done using the local ranking profile, not the
remote profile. The selection of target peers had been enhanced, now all
robinson peers which have a solr interface are searched using that
interface rather with the old YaCy interface. There should also an
enhancement in indexing speed as there are less requests to the solr for
doing that and index updates are bundled together while forced commits
had been reduced using a new solr 4.1 soft-commit feature. There had
also been fixes to some memory leaks and the overall memory usage should
be lower. Finally, the logging had been renovated and logs are now done
using only the java-logger. All libraries, using different loggin
technology are routed to the java logger using logging gateways. The
complete number of log entries for solr updates had been strongly
reduced since these many logging entries had become a perfomance issue
in 1.3.
