2d36a7eaf5 - do not create a new query for all remote peers
- no document search this time
- adjusted banner and network to not show 'WORDS' but DHT Chunks. This
is to avoid confusion for robinson peers which do not create Word

9c09fd7d0b better/less requests to local solr; the request is made in chunks which
are exactly at only that size which is needed to present the current
search result page. This will also cause that next solr request are made
automatically during switching to next pages.

c95a84103a complete redesign of search process:
- removed 'worker' processes
- no internal time-out behaviour: methods either are successful or
return null
- waiting is only done on top-level
- removed snippet-production; this is replaced by solr snippets
- removed statistics based on solr size queries (they had been VERY
long); the statistics (like suggestions or tag cloud) are now again
based on the old but very fast RWI index. In portal or intranet mode the
RWI index is usually switched off; if you like to have statistics again
then you must switch on the rwis again in this mode.
- fixed many bugs regarding correct page counter

91a0401d59 introduced a second core named 'webgraph'. This core will hold the link
structure, but is not filled yet. To have the opportunity of a second
core, multi-core functionality had to be implemented to the
deep-embedded solr:
- migrated the solr_40 directory content to a subdirectory
'collection1'; the previously used default core is now called
collection1
- added solr_40/webgraph subdirectory as second core
- added a servlet configuration for the second core 'webgraph' in
/IndexSchema_p.html
- added instance handling as addition to solr connections: all solr
connectors are now instances of an solr 'instance' object; this required
a complete re-design of the solr embedding
- migrated also caching and sharding ontop of new instance handling
- migrated the search apis to handle now the access to a specific core,
the default core named 'collection1'
- migrated the remote solr search interface to access shards of cores;
for the yacy remote search the default core is now called 'solr'; using
the peer address as solr address
- migrated the solr backup and restore process: old backups cannot be
used after this migration!
- redesign of solr instance handling in all methods which access the
instances: they cannot hold copies of these instances any more; the must
retrieve the actuall connection object every time they want to write to
it (this solves also some bugs when switching the index/network)
- added another schema 'solr.webgraph.schema', the old solr.keys.list is
replaced by solr.collection.schema

c34af7fe94 extended JSON Response Writer and Opensearch Response Writer for the
Solr search interface in such way that it is possible to use this
interface for the yacyinteractive search. This search interface is now
much faster using the Solr search directly. For the Solr interface it
was necessary to create a translation from the YaCy search modifiers to
the Solr facet selection. This was added in such a way that it becomes
generic for the normal YaCy search and as a on-top evaluation for Solr
queries.

e1da39245a when searching the network, do not search on robinson peers with the old
DHT search interface. Now use the solr interface.

01200f06cc using the author field as solr-native facet. this makes it necessary to
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.

d48e9788d2 enhanced search result processing behavior
- query less at one time; query more often
- in between the small queries, evaluate results
- remove fields from search results which are not needed

5dfd6359cb redesign of the QueryParams class: introduced QueryGoal which holds the
query string parser. This shall be used to create a proper full-string
matching which is handled then by QueryGoal.

2371ef031c added solr faceted search support to YaCy search results
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

f8f05ecba7 - added a delete button in host browser to delete a complete subpath
- removed storage of default collection name - default is now "user"

562183932b - removed ip_s from default profile since that needs a DNS lookup to
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)

ff3eaa21b0 added remote search to solr on YaCy peers!
- 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

done automatically

f8cd57c92f new indexing strategy: ALL links that appear anywhere are indexed, not
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

0797b0de99 new handling of remote search processes: looking for seeds will now not
block the whole search process any more. A deadlock with a DHT selection
process may have been the cause for interface lockings in the past.
