For finer control over which parsed documents can trigger an addition of
their links to the crawl stack, complementary to the existing crawl
depth parameter.
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.
Acces rate limitations to this search mode by unauthenticated users are
set low by default to prevent unwanted server overload but can be
customized through the SearchAccessRate_p.html configuration page
Fixes#291
For better support of the search page usage with JavaScript disabled.
Reduces also the number of initial refreshes of the paginations links.
When JavaScript is enabled, pagination links are still regularly
refreshed until all the search feeds are terminated on server side.
Non regressions tested on the following platforms :
Linux Debian Stretch :
- Firefox 60.5.1esr
- Chromium 72.0.3626.96
Windows 10 :
- Firefox 65.0.1
- Chrome 72.0.3626.109
- Edge 25.10586.672.0
- IE 11.1540.10586.0
Mac OS :
- Safari 11.0
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.
- set the chunksize to 100 to meet the max of the embedded solr
- re-enable sorting (the case where we switched it of should be away)
- enable recrawling on remote-solr
On some conditions (especially when reaching timeout), concurrent Solr
query tasks used by the /HostBrowser.html and /api/linkstructure.json
never terminated, thus leaking resources, as reported by @Vort in issue
#246
New "Media Type detection" section in the advanced crawl start page
allow to choose between :
- not loading URLs with unknown or unsupported file extension without
checking the actual Media Type (relying Content-Type header for now).
This was the old default behavior, faster, but not really accurate.
- always cross check URL file extension against the actual Media Type.
This lets properly parse URLs ending with an apparently odd file
extension, but which have actually a supported Media Type such as
text/html.
Sample URLs with misleading file extensions added as documentation in
the crawl start page.
fixes issue #244
Not using the JDK URLDecoder.decode() function, as it strips '+'
characters when they occur after '?' (both characters having regular
expression semantics when used in blacklist path patterns)
Normalize blacklist path patterns using percent-encoding, at pattern
edition in web interface and at loading from configuration files.
Fixes issue #237
- To meet current browsers security rules, which prevent selecting a
full file path with an html input field of type 'file'
- As it does not make sense to select a local file path when a the
administered YaCy server is remote (not on the same computer as the
browser)
Considering that the sliders usage on that page is very basic, using
standard HTML5 inputs of type "range" has here the following advantages
:
- better keyboard accessibility
- remove not very necessary additional jquery dependencies
Today browsers suport for range inputs is good, and even on old
unsupporting browsers such as IE < 10 they nicely fall back to text
inputs.
When searching images, thumbnails that could not be rendered (because of
a load error such as HTTP 404, networking issue or an internal error on
the rendering servlet) are now hidden as default. But can be revealed
with a button if desired.
Fix for issue #217
Manually replacing '+' character or "%20" by a space character in the
search query parameter was necessary in YaCy a long time ago to properly
decode application/x-www-form-urlencoded format (commit
9842fab6e4 in 2010).
Since the introduction of Jetty as the embedded HTTP server (commit
4b77733e59 in 2013), this is no more
necessary as Jetty internals already do this for us in
org.eclipse.jetty.util.UrlEncoded.decodeUtf8To().
So we can remove now this duplicated decoding as it prevents a proper
use of the '+' character in search requests, as reported in issue #216.
The status of the library in the DictionaryLoader_p.html page now also
advertises the user that an upgrade can be applied when an older dump is
already loaded.
Upgrade applied as suggested by Niklas Andrus @fapth_gitlab on Gitter
chat.
SimpleDateFormat must not be used by concurrent threads without
synchronization for parsing or formating dates as it is not thread-safe
(internally holds a calendar instance that is not synchronized).
Prefer now DateTimeFormatter when possible as it is thread-safe without
concurrent access performance bottleneck (does not internally use
synchronization locks).

This makes possbile to set up much more advanced document crawl filters,
by filtering on one or more document indexed fields before inserting in
the index.
If not interested in displaying this on your search results and notably
on a peer with limited resources this can help saving some CPU and
outgoing network connections.
By not generating MD5 hashes on all words of indexed texts, processing
time is reduced by 30 to 50% on indexed documents with more than 1Mbytes
of plain text.
Ensuring http post method is used for operations with server-side
effects (in respect of http semantics), and a valid transaction token is
provided by the user-agent.
- to prevent unwanted exposure of index entries about private
local/intranet documents when switching from "Intranet Indexing" mode
while attached to remote Solr instance(s)
- to warn user about remote Solr instance(s) still attached when
switching from modes other than "Intranet Indexing"
- properly handle IPv6 loopback address replacement
- replace loopback address or host only when accessing peer remotely
- replace loopback part with the peer hostname as requested rather than
with its seed public IP as this works better for Intranet mode and when
peer is behind a reverse proxy.
Otherwise once this operation is applied, the remote Solr(s) instances
are deconnected and the embedded Solr is connected even if disabled by
setting "core.service.fulltext".
Also use constants for related default setting values.
This is necessary when you want to attach to a dedicated external Solr
server protected with basic http authentication and requested over https
but having only a self-signed certificate.
When inlined (for example in the CrawlProfileEditor_p.html page) :
search only on the comment, as the url is not visible
On regular display : search on comment OR url, instead of comment AND
url. Otherwise searching on comments terms is almost useless as these
terms are not necessarily present in the url.
Applied the same default results page size as when a type filter is
defined for proper and consistend page navigation when combining type
filter and search query.
Otherwise, when interested in viewing `Link List` for example, each time
you typed a new URL, `Parsed Sentences` view mode was selected as
default and you had to selected again the view mode you are insterested
in.
As discussed in issue #160 , blacklist entries can indeed currently not
be "complete" regular expressions, but must be structured as a domain
part, a separator character ('/'), and a path part.
- Fixes issue #160 : handle properly syntax exceptions with a user
friendly message
- Fixes loss of information on multiple blacklist entries editions
- Fixes loss of entries when moving entries from one list to another
Previously, when clicking a selected facet in the search results page to
unselect it, all other eventually selected modifiers/facets were also
removed.
With the appropriate vocabulary settings in Vocabulary_p.html page, this
can produce Vocabulary search facets displaying item types referenced in
html documents by microdata annotation.
Tested notably, but not limited to, vocabulary classes/types defined by
Schema.org and Dublin Core.
