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.
This page was already no more XHTML 1.0 as it makes use of the HTML5
<progress> element.
Applied current HTML standard recommended Doctype declaration (see
https://www.w3.org/TR/html/syntax.html#the-doctype ).
- added a servlet api/linkstructure.json which generates a link graph
information in json
- added a javascript link graph renderer hypertree.js using d3 and the
new servlet linkstructure.json
- embedded the new link graph in the crawler monitor and the host
browser
- adopted all YaCy administration pages to new framework
- created new search page layout (working, but still work in progress)
- old skin files are fully appliable! (and looking good)
- target is a new style based on bootstrap examples, see /test.html
- icons in YaCy may be replaced by glyphicons (to be done)
The default schema uses only some of them and the resting search index
has now the following properties:
- webgraph size will have about 40 times as much entries as default
index
- the complete index size will increase and may be about the double size
of current amount
As testing showed, not much indexing performance is lost. The default
index will be smaller (moved fields out of it); thus searching
can be faster.
The new index will cause that some old parts in YaCy can be removed,
i.e. specialized webgraph data and the noload crawler. The new index
will make it possible to:
- search within link texts of linked but not indexed documents (about 20
times of document index in size!!)
- get a very detailed link graph
- enhance ranking using a complete link graph
To get the full access to the new index, the API to solr has now two
access points: one with attribute core=collection1 for the default
search index and core=webgraph to the new webgraph search index. This is
also avaiable for p2p operation but client access is not yet
implemented.
- the list of urls is entered in the expert crawl start in a textfield;
the one-line input field was replaced with a text box
- start urls can also be given in one single line where the urls are
separated by a '|'-character
- as an effect, the crawl profile cannot carry a single start url for
identificaton because it is possible to have more. Therefore the url was
removed from the crawl profile
- this affect all servlets which display a crawl profile: removed the
url field from all there servlets
- to work consistently with several start urls and the other crawl
starts which computed crawl start url lists from sitelists or sitemaps,
the crawl start servlet was restructured completely
- new rules for must-match patterns were created to make it possible
that site crawl starts also work with several crawl starts at once
ready-prepared crawl list but at the stacks of the domains that are
stored for balanced crawling. This affects also the balancer since that
does not need to prepare the pre-selected crawl list for monitoring. As
a effect:
- it is no more possible to see the correct order of next to-be-crawled
links, since that depends on the actual state of the balancer stack the
next time another url is requested for loading
- the balancer works better since the next url can be selected according
to the current situation and not according to a pre-selected order.
