technique should not be used at all! This project is about privacy, the
existence of a click servlet is one example why people should NOT use a
search portal if such exists.
This is intended for peers who want to participate in the P2P network but don't wish to load/fill-up their index with metadata of every received search result.
The DHT transfer is not effected by this option (and will work as usual, so that a peer disabling the new store to index switch still receives and holds the metadata according to DHT rules).
Downside for the local peer is that search speed will not improve if search terms are only avail. remote or by quick hits in local index.
To be able to improve the local index a Click-Servlet option was added additionally.
If switched on, all search result links point to this servlet, which forwards the users browser (by html header) to the desired page and feeds the page to the fulltext-index.
The servlet accepts a parameter defining the action to perform (see defaults/web.xml, index, crawl, crawllinks)
The option check-boxes are placed in ConfigPortal.html
so web.xml in defaults dir is applied first and optional DATA/SETTINGS/web.xml loaded on top.
By using this Jetty feature (default web.xml) we assure that changes to the default are applied to existing installations
and individual addition/changes are still respected.
preferred over https. While this is a bad idea from the standpoint of
security it is more common applicable for environments where http and
https mix and for some domains https is not available. Then the
double-check is possible even if no postprocessing is performed.
from documents which actually are inside the index. This can be
reproduced using the crawl result table at
http://localhost:8090/CrawlResults.html?process=5
The cache is temporary disabled to remove the bad behaviour, however a
later reactivation of that feater may be possible.
notions within the fulltext of a document. This class attempts to
identify also dates given abbreviated or with missing year or described
with names for special days, like 'Halloween'. In case that a date has
no year given, the current year and following years are considered.
This process is therefore able to identify a large set of dates to a
document, either because there are several dates given in the document
or the date is ambiguous. Four new Solr fields are used to store the
parsing result:
dates_in_content_sxt:
if date expressions can be found in the content, these dates are listed
here in order of the appearances
dates_in_content_count_i:
the number of entries in dates_in_content_sxt
date_in_content_min_dt:
if dates_in_content_sxt is filled, this contains the oldest date from
the list of available dates
#date_in_content_max_dt:
if dates_in_content_sxt is filled, this contains the youngest date from
the list of available dates, that may also be possibly in the future
These fields are deactiviated by default because the evaluation of
regular expressions to detect the date is yet too CPU intensive. Maybe
future enhancements will cause that this is switched on by default.
The purpose of these fields is the creation of calendar-like search
facets, to be implemented next.
TimeoutRequests. The purpose is to test if YaCy runs better on VMs where
there is a limitation of concurrent processes; see
/proc/user_beancounters in row numproc; this value is limited and should
be low. Try to set timeoutrequests to keep this low. (works only after
restart)
set to 'Always Fresh' the cache is always used if the entry in the cache
exist. This is a good way to archive web content and access it without
going online again in case the documents exist.
To do so, open /Settings_p.html?page=ProxyAccess and check the "Always
Fresh" checkbox.
This is set do false which behave as set before.
If you set this to true, then you have your web archive in DATA/HTCACHE.
Copy this to carry around your private copy of the internet!
if file in DATA/SETTINGS it is loaded otherwise file in ./defaults is loaded
(if locale ./defaults/stopwords.xx doesn't exist take solr/lang/stopwords_xx.txt as default)
move yacy.stopwords, yacy.stopwords.de and yacy.badwords.example out of root directory to ./defaults directory
This is the first element of a new 'decoration' component which may hold
switches for different external appearance parameters.
The first switch in that context is decoration.audio (as usual in
yacy.init). This value is set to false by default, that means the audio
feedback element is switched off by default. To switch it on, set
decoration.audio = true (using /ConfigProperties_p.html). You will then
hear sounds for the following events:
- remote searches
- incoming dht transmissions
- new documents from the crawler
Sound clips are stored in htroot/env/soundclips/ which is done so
because a future implementation will read these files using the http
client and with configurable urls which will make it very easy for the
user to replace the given sounds with own sounds.
string which is visible in the browser. That makes it possible that the
browser instructs the user how to change a forgotten admin password
(during runtime).
- 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
attribute in the <a> tag for each crawl. This introduces a lot of
changes because it extends the usage of the AnchorURL Object type which
now also has a different toString method that the underlying
DigestURL.toString. It is therefore not advised to use .toString at all
for urls, just just toNormalform(false) instead.
Filter queries are not actually related to ranking, but user requests
have pointed out that specific boost queries to move results to the end
of the result list are not sufficient. Such boost filters may be better
executed as actual filter and therefore such a filter can now be
statically applied to every search request. A typical use could be the
expression "http_unique_b:true AND www_unique_b:true" which uses the
recently introduced fields http_unique_b and www_unique_b which are true
only for one of the alternatives with/without http(s) and with/without
prefix 'www.' in host names.
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
