hold a date for each URL to record when a url was first seen. This is
then used to overwrite the modification date for urls upon recrawl in
case that the first-seen date is before the latest document date. This
behaviour is necessary due to the common behaviour of content management
systems which attach always the current date to all documents. Using the
firstSeen database it is possible to approximate a real first document
creation date in case that the crawler starts frequently for the same
domain. As a result the search results ordered by date have a much
better quality and the usage of YaCy as search agent for latest news has
a better quality.
- 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)
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.
output writer. This made the creation of a html result writer necessary
which is included in this commit. The yacydoc servlet was used to
present all metadata to a document, but the solr interface can serve for
this purpose in a much better way. All usages (instead one) of yacydoc
were replaced by a solr call. This affects also the 'metadata' link
attached to search results.
API recording for this method so it can be repeated automatically. The
index dump generation is now also available for API recording. Added
some synchronization in backend which was necessary for this.
index (new solr core webgraph) .. this is now off by default
- completely redesigned this servlet
- added description how to attach a remote solr
- adjusted naming of servlet and menues
- moved 'lazy initialization' attribut from IndexSchema to
IndexFederated (this is a general option) back again.
metadata and old rwi and for the citation index. The important
advancement is the separation of the citation index deletion because
that index is responsible for the linkdepth calculation. Now a search
index can be deleted without the citation index and that should cause
that less clickdepths must be post-processed.
IndexControlURLs where it appears more naturally. Because the RWI
administration is less important in the presence of Solr, the
IndexControlURL is now the default servlet when the Index Administration
button on the main menu is selected.
the segments had been there to create a tenant-infrastructure but were
never be used since that was all much too complex. There will be a
replacement using a solr navigation using a segment field in the search
index.

This is a major change in the organization of indexes.
Please consider a back-up of your data before you run this update.
All existing index files will be moved and renamed to a new position.
With this change, it will be possible to maintain different indexes for different purposes and it will be possible to have a distinction between DHT-in and DHT-out specific indexes. Tenants may also have their own index, and it may be possible to have histories and back-ups of indexes. This is just the beginning, many servlets must be adopted after this change, but all functions that had been there should still work.

- fixes to httpd server response header generation
- fixes to a server date computation bug
- new Button in indexControl to view content of url in ViewFile

- added two new api files for document metadata:
- added a XHTML+RDFa html file shows the document metadata in a format that presents the data for rendering and for metadata retrieval. This is a typical document format for a semantic web data structure. the used RDF vocabulary is Dublin Core
- added a xml file that shows the same data as pure DC metadata
- integrated the API into the existing IndexControlURLs interface
With about one billion metadata files (URL metadata) this extension makes the freeworld YaCy network
to one of the probably largest metadata document provider for the semantic web!

- added 'delete all' button to all results of such a domain statistic output which causes that all urls to this domain are deleted
- extended stack cleaner to clean also the statistics: they are not completely destroyed, only the smallest counting domains are removed

to do this, the index administration interface was extended.
It is now possible to select parts of a index.
See properties shown in interface after a word search for details.
