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.
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!
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).
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
resource.disk.used.max.overshot by 4 times because first users reached
that limit and wondered why the crawler was paused automatically :)
The crawler will now stop at 2TB disk usage :)
- removed the default version blacklist regex from init (for future versions)
!!! left existing update blacklist setting untouched !!!
(existing installation wanting autoupdate for 1.71 need to change blacklist in ConfigUpdate_p.html)
- moved old blacklist patch to migration.java
config settings frome the page also removed from yacy.init
augmentation.reflect
augmentation.addDoctype

is VERY high. This applies also if the CPU load is high because of
in-cache crawling; in that case we want to experience a high-CPU load as
much as possible
The resource observer is now able to recognize free disk space AND
available space for YaCy. The amount of space which is assigned for YaCy
are defined in new settings in the configuration file.
Furthermore, there is now a cleanup process which deletes files in case
that an autodelete is activated. The autodelete is now BY DEFAULT ON if
the disk space is low, which means that YaCy starts to delete documents
when the disk is full!
if load > 1 (but < 2) but only if there is enough memory (now: 0.5 GB
RAM available). The memory amount of the postprocessing is the cause
that systems block because they run into a frequent-GC chain which
almost locks the peer. If running with enough memory, the postprocessing
is fast and not damaging to the system.
Because the required RAM of 0.5 GB is never available in default
setting, the postprocessing will not run if the peer is not reconfigured
to use more memory.
introduced, it was also used for search facets. The generic search
facets are now deduced from generic solr fields which makes jena as tool
for facet semantics superfluous.
