When unauthenticated (or with insufficient rights) client is blocked
either because blacklisted or excessive request rate, render an error
message and a relevant HTTP status for API requests, instead of an empty
response that appears broken.
Previously search navigators/facets elements were sorted only by counts.
Now from the ConfigSearchPage_p.html admin page, sort direction
(ascending/descending) and type (on counts or labels) can be customized
independently for each navigator.
Previously, when clicking a selected facet in the search results page to
unselect it, all other eventually selected modifiers/facets were also
removed.
Also ensure authentication is not lost by Digest timeout when navigating
between index.html and search results page.
This way, running searches with extended features on a remote peer or a
password protected peer works with a regular user (with "Extended
search" rights).
When authenticating on the search page with a user without "Extended
search" rights, it appears as authenticated, but has just its usual
access to the public search features.
The SearchEvent listen to changes on each of its navigators, and the
information about their overall state is sent with each fetched search
item (as a "data-nav-generation" attribute). Then the browser can
regularly fetch a fresh version of yacysearchtrailer.html only if
necessary (when that nav-generation value change).
This is a fix for mantis 766 ( http://mantis.tokeek.de/view.php?id=766 )
Since the upgrade to Digest authentication, access to protected search
features was indeed disabled once the Digest nonce timed out.
After Digest auth timeout the browser no more sent authentication
information and as the search results page is not private, protected
features were simply be hidden without asking browser again for
authentication.
Adding a supplementary parameter when accessing the search results as
authenticated fixes this.
- added some missing increments from RWI results
- decrement relevant navigator counts when solr or RWI results are
evicted because duplicates detection or constraints checked belatedly
- do not compute facets when unnecessary to avoid unwanted CPU load
- do not increment from facets when already done
- do not rely on facets on remote solr peers requests, as most of the
time only a limited part of their total results if fetched (thus also
preventing unnecessary load on remote peers)
- use a concurrency friendly score map for the dates navigators to
prevent unwanted ConcurrentModificationExceptions
This improves the situation for the most obvious inconsistencies in
search navigators counts, but more has to be done for a true accuracy
(notably when query modifiers constraints are applied belatedly - after
the solr or RWI retrieval request - such as the content domain
constraint)
count.
This might be tangential related to http://mantis.tokeek.de/view.php?id=736
as the example includes a local index search, while rwi results are not
counted.
to not already actives.
Dht results are now included in count this might over shoot on redundant
dht and solr, while the previous solr facet based was always low.
It can take any Date field of the index and displays a list of year strings
in reverse order by the year (not the score/count).
To allow to define the index field to use, the fieldname (and title can be
appended to the navi's name "year" e.g. year:load_date_dt:LoadDate
It works also with dates_in_content_dts field (from the graphical date
navigator). Here the query parameter from: to: are used on selection as
Query modifier (for other dates currently no query parameter available, so
selection won't work to filter search results).
Not included in the UI Searchpage layout config so far (for experiment with
it manual change to conf needed).
the navigator to include counts all matches (rwi+fulltext).
Fixing also unresolved_pattern in navigators title (of the counter)
The use of inurl: query modifier as filter has not been changed keeping
it as soft (unsharp) filter facet.
Upd StringNavigator to prevent empty string form multivalued solr fields,
removed date value conversion (better handled elsewhere, not need here).
Prepared the first basic navigators (for authors and collections) for the
list of SearchEvent.navigatorPlugins and adjusted servlet to use these.
- this allows to configure display order of these navigators (by ordering config string)
- eventually allows for additional and/or custom navigators using any
available index field without need for changing servlets
- the Collection navigation has been adjusted to exclude the internal,
default robot_* and dht collections from displaying
- rwi results are now also checked for navigatior by the refactored navi's
So far no config options were added to customize or add navigators (may
come later if route of upcoming modularization/plugin system is defined).
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.
collections in search result. When selecting one of them in another
search, switch off the previously selected collection. This actually
turns the collection navigation modifier into a radio-button like
behaviour
- switch automatically on upon load of geodata provider
- but allow switch on also without geodata file (and display the location nav if search result has lat/lon location)
- if less or equal of 8 facet options are present, they are shown by
default
- if more facet options are present, they are hidden
To view or hide all facets, just click on the facet header bar
- date navigation
The date is taken from the CONTENT of the documents / web pages, NOT
from a date submitted in the context of metadata (i.e. http header or
html head form). This makes it possible to search for documents in the
future, i.e. when documents contain event descriptions for future
events.
The date is written to an index field which is now enabled by default.
All documents are scanned for contained date mentions.
To visualize the dates for a specific search results, a histogram
showing the number of documents for each day is displayed. To render
these histograms the morris.js library is used. Morris.js requires also
raphael.js which is now also integrated in YaCy.
The histogram is now also displayed in the index browser by default.
To select a specific range from a search result, the following modifiers
had been introduced:
from:<date>
to:<date>
These modifiers can be used separately (i.e. only 'from' or only 'to')
to describe an open interval or combined to have a closed interval. Both
dates are inclusive. To select a specific single date only, use the
'to:' - modifier.
The histogram shows blue and green lines; the green lines denot weekend
days (saturday and sunday).
Clicking on bars in the histogram has the following reaction:
1st click: add a from:<date> modifier for the date of the bar
2nd click: add a to:<date> modifier for the date of the bar
3rd click: remove from and date modifier and set a on:<date> for the bar
When the on:<date> modifier is used, the histogram shows an unlimited
time period. This makes it possible to click again (4th click) which is
then interpreted as a 1st click again (sets a from modifier).
The display feature is NOT switched on by default; to switch it on use
the /ConfigSearchPage_p.html servlet.
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)
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
