generic parser but extracts links like the htmlParser. This should be
used for ASCII documents without known text format annotation like
source code files or json documents. Probably also good for xml files
without known schema.
- close stackfile inputstream at end of ChunkIterator
This should solve startup delay while unfinished crawl jobs exist (maybe also too many open file situation)
was optional and another alternative metadata store was available. Since
that store is now removed, Solr is always available (internally or
externally)
and adjusted xslt, for solr snippets (&hl=true) to decode the xml encoded html <b> tag by adding disable-output-escaping
(still open item description may be double as dc: tag and rss.description tag)
- author facet is based on omitted author_sxt field
- adjust to make author nav available on exist of author field but keep using author_sxt to construct the facet (why!?)
- add check for querymodifier author in searchevent
- Web servers may now deliver YaCy-specific http header field with a
title and keywords. The new http header fields are:
X-YaCy-Media-Title - to be used for media (image, audio, video) titles
X-YaCy-Media-Keywords - to be used for media (image, audio, video)
keywords
- both fields are written to document fields title and keywords and are
searched also during image search.
- to make the usage of arbitrary http header fields (including this new
fields) possible in the /api/push_p.json servlet, a new POST argument is
also introduced to push http header fields. The new POST attribute is
named "responseHeader-X" (where X is the counter). It is allowed to use
this attribute as multi-attribute several times, each can be filled with
a http header line.
- see /api/push_p.html for examples
- to allow manually renew index content for this url (e.g. in case it is a remote search result with metadata only)
- use simply a QuickCrawlLink_p javascript snippet (minimalistic 1st solution)
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
crawling to the YaCy indexer. Files are uploaded using POST multipart
requests; multiple file uploads are possible as well. Each file has
attached the file date and mime type which is used to get the right
parser for the submitted data. Also an url is submitted which is
assigned to the document.
The CrawlSwitchboard has a new option for default Crawl Profiles which
are assigned dynamically from the new push interface.
