- 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)
- 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.
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
works fine to restrict language for local solrSearches.
More work needs to be done to make rwi/remote searches respect the modifier.language restriction.
because it's normal that a boolean value is missing in the post argument
if a checkbox is not selected.
Added also some style enhancements to IndexFederated, removed the Solr
attachment manual and replaced it with a link to the wiki which explains
this in more detail.
jdk-based logger tend to block
at java.util.logging.Logger.log(Logger.java:476) in concurrent
environments. This makes logging a main performance issue. To overcome
this problem, this is a add-on to jdk logging to put log entries on a
concurrent message queue and log the messages one by one using a
separate process.
- FTPClient uses the concurrent logging instead of the log4j logger
explored for citations within other documents. A click on the
'Citations' link shows an analysis with all text lines in the document
each with a complete list of documents which contain the same line. A
second section shows the linking documents in ascending order of number
of citations from the original document. Because documents from
different hosts are most interesting here, they are listed at the top of
the page as possible 'copypasta' source.
- added additional config page (ConfigSearchPage_p) for easy setup of search page layout (to not overload ConfigPortal page)
- currently redundant setting with part of ConfigPortal page
- added missing config for filetype and protocol navigator
- adjusted init of SearchEvent to check navigation config setting
- renamed RankigProcess.getTopicNavigator to getTopics (to distiguish between added SearchEvent.getTopicNavigator)
