the embedded Solr (the default). This was obtained by cirumventing solrj
search encapsulation and the implementation of direct index access
methods to Solr.
The effect will not only be seen during search, but this has also a
strong effect on suggestions (much more) and less CPU power usage during
index distribution (which needs many search requests)
- transformed log lines to String before they are stored because the
storage space is about 1:250 (45kb for one line before transformation,
180 bytes afterwards)
- this saves up to 10MB RAM so we can increase the number of lines to
1000 again.
which had a problem because of badly used concurrency.
This fix also caused a redesign of the whole host deletion process.
This should fix bug http://bugs.yacy.net/view.php?id=250
the right content domain (i.e. identifying that it is an image, text
etc.) because it used the file extension and not an existing mime type
assignment.
- fixed the new setting that images shall be loaded for a better image
search.
- both fixes together makes it now possible to crawl
commons.wikimedia.org which makes use of 'funny' document names (i.e.
ending with .jpg while the document is html)
may have contained multiple same expressions within the disjunction of
domain-restrictions. This fix removes the redundant restrictions and
makes the regex shorter.
This shall fulfill the following requirement:
If a document A links to B and B contains a 'canonical C', then the
citation rank computation shall consider that A links to C and B does
not link to C.
To do so, we first must collect all canonical links, find all references
to them, get the anchor list of the documents and patch the citation
reference of these links.
are deleted to terminate the crawl because otherwise the crawl will go
on after the load-from-passive stack policy.
- better check if a crawl is terminated using the loader queue.
since httpclient uses the domain-cache it is useful not to clean the
domain cache until crawling is running (domains are filled into this
cache)
On huge crawl-starts (eg. from file) my DNS did not follow the high
rates - so I reduced the rate and give some more time(-out)
webgraph index which is temporary filled with the crawl profile key.
This is used to select a set of documents for post-processing as soon as
a crawl is finished. Now the postprocessing for a specific crawl is
started when that specific crawl is finished and not at the end of all
post-processing steps.
profiles are cleaned. This shall enable a profile-termination-driven
postprocessing. To do this, index writings must carry the profile key
which will be implemented in another (next) step.
is visible whenever a location is available in the search result.
To activate this, the search.navigation property in yacy.conf must be
modified to the new default values.
there for deletion), this fixes a problem for the deletion of old
documents for new crawl starts
- added clickdepth and citation computation for fail documents
- replaced load failure logging by information which is stored in Solr
- fixed a bug with crawling of feeds: added must-match pattern
application to feed urls to filter out such urls which shall not be in a
wanted domain
- delegatedURLs, which also used ZURLs are now temporary objects in
memory
for anchor attributes.
- this caused that large portions of the parser code had to be adopted
as well
- added a counter target_order_i for anchor links in webgraph
computation
all unique links! This made it necessary, that a large portion of the
parser and link processing classes must be adopted to carry a different
type of link collection which carry a property attribute which are
attached to web anchors.
- introduction of a new URL class, AnchorURL
- the other url classes, DigestURI and MultiProtocolURI had been renamed
and refactored to fit into a new document package schema, document.id
- cleanup of net.yacy.cora.document package and refactoring
html meta fields to get a correct (or: better) date timestamp. The
http:last-modified mostly does not work because it is set to the current
date from most CMS.
fuzzy_signature_copycount_i, which count the number of copies of
non-unique documents and assigns this to each document. Thus, each
document there is a number assigned which shows how many copies of this
document exists.
These fields are disabled by default.
like normal documents. Using this option (by default on at this moment;
this might change soon) it is possible to get the exif data into the
search index to be used in image search.
