Fixes issue #90 for local queries only: Stealth mode, Portal mode or
Intranet mode.
For P2p mode, the issue would probably be difficult to solve with
reasonable performance. This is still to dig.
Also switched some InterreputedException catch log messages to warn
level as this is normal behavior when shutting down a peer.
Fixed yacysearch buttons navbar behavior to deal correctly with total
results count or offset over 1000. Also improved the buttons navbar to
be able to navigate over 10th page for local queries.
to make all readily available information from the original ServletRequest
available to YaCy servlets (without converting data to internal structures).
The implementation of the common interface allows easier integration of
YaCy servlets with the servlet standard (e.g. shared login service with
the servlet container etc.)
taking the existing limits into account but make it consistent with search option screen for admin and public user
changes:
- configured default number of items per page (ConfigPortal_p.html) is used as is (no hardcoded limit)
- otherwise requests are limited to 100 results per page ( = search option, index.html)
(this basically is the major change, inc. limit from 20 to 100 for public user)
P.S. - the older grant of more (1000), if no online snippet calculation, is kept (for the time being)

bayesian filters. This can be used to classify documents during
indexing-time using a pre-definied bayesian filter.
New wordings:
- a context is a class where different categories are possible. The
context name is equal to a facet name.
- a category is a facet type within a facet navigation. Each context
must have several categories, at least one custom name (things you want
to discover) and one with the exact name "negative".
To use this, you must do:
- for each context, you must create a directory within
DATA/CLASSIFICATION with the name of the context (the facet name)
- within each context directory, you must create text files with one
document each per line for every categroy. One of these categories MUST
have the name 'negative.txt'.
Then, each new document is classified to match within one of the given
categories for each context.
index has more than two million documents. This protects the index from
beeing flooded with search requests that cannot be resolved before the
real search query has to be computet.
to support the new time parser and search functions in YaCy a high
precision detection of date and time on the day is necessary. That
requires that the time zone of the document content and the time zone of
the user, doing a search, is detected. The time zone of the search
request is done automatically using the browsers time zone offset which
is delivered to the search request automatically and invisible to the
user. The time zone for the content of web pages cannot be detected
automatically and must be an attribute of crawl starts. The advanced
crawl start now provides an input field to set the time zone in minutes
as an offset number. All parsers must get a time zone offset passed, so
this required the change of the parser java api. A lot of other changes
had been made which corrects the wrong handling of dates in YaCy which
was to add a correction based on the time zone of the server. Now no
correction is added and all dates in YaCy are UTC/GMT time zone, a
normalized time zone for all peers.
introduce FederateSearchManager handling search heuristic to external systems via specific FederateSearchConnectors,
which provide the query() functionallity, the translation to YaCy schema .toYaCySchema() and the search() routine to deliver results to searchevents, which is generally implemented in Abstract connector.
The manager enforces now a min 15s delay between calls to external systems.
Besides the OpensearchConnector a SolrFederateSearchConnector is available. It uses a additional config file for fieldname translation.
default heuristicopensearch.conf:
- openbdb.com removed - seems not longer to deliver results
- config via solrconnector to datacite.org added (large technical library archive)
it acts on YMarks but YMark interface seems not maintained,
for future features (e.g. query memory) BookmarkDB is the likely choice to expand, besides the crawlstart bookmark also the result bookmark icon now adds to BookmarkDB.
The YMark related code is (for now) left untouched so both tables are updated.
*) will try other ports if YaCy standard ports are not available
*) distinguish between internal and external port (not sure if this
works 100%)
Still to add: propery in config to enter own external port (in case of
manually configured NAT)
used parameter &cat=image is obsolete and returns no results
- remove &cat=image and &cat=href references
- remove &tenant= references (unused)
Use contentdom=image and inurl: parameter to make showPicture link display something (open in new window because of used inurl modifier changes original query)
done. This makes it possible to search all documents on a single domain
even if no search word is given. This is in particular interesting when
searching for all images on a single domain.
- remove verify=cacheonly from admin screen search box to use the configured values
(otherwise definition overwrites configured behavior and is used for following searches what might give unexpected/confusing different results compared to using /yacysearch )
- with search modifier /heuristic a request is send to all configured opensearch target systems (old /heuristic/blekko modifier not longer valid)
- this allows to use opensearch heuristic on individual search request (in contrast to configuration HEURISTIC_OPENSEARCH=true which sends a osd request on all global searches
- the index.html searchoption text adjusted to be displayed only if option configured
- add Archive-It to predefined systems
The collection field (can be filled i.e. in Crawl Start) can be used to
add categories to YaCy index entries. The usage of that field was
restricted to solr searches and post argument filters as implemented in
commit f7571386a3.
This commit extends collections to a full navigation option in the
standard YaCy search interface. The field is not active by default but
can be activated easily in the /ConfigSearchPage_p.html servlet (just
check the 'Collection' facet field). Collections can now be used for (at
least) two purposes:
- to provide search tenants (through post argument collection)
- to provide self-made category navigation
Search requests may now have (independently from switched on or off
collection facet) a "collection:<collection-name>" modifier attached;
firthermore collection names may use disjunctions using the '|' pipe
symbol. For example, this is a valid search request:
www collection:user|proxy
