- when using a site operator search for a domain where the domain has a
www prefix, also the domain without the www is enclosed
- when using a site operator search for a domain where the domain has no
www prefix, also the domain with the www in enclosed
- in the host navigator, all domains with and without a www prefix are
accumulated. That means that the host navigator does never show a host
with a www prefix.
This should prevent usage mistakes of the site operator.

The feature was not called 'haslink' but called 'inlink' to have a
analogous naming like 'inurl'. This causes now that you can search for
words in links of the document, like:
* inlink:yacy
searches all documents which link to pages which have an 'yacy' in the
url.
- migrates all entries in old urldb
Metadata coordinate (lat / lon) NumberFormatException still relative often (see excerpt below),
- added try/catch for URIMetadataRow (seems not to be needed in URIMetaDataNode, as Solr internally checks for number format)
- removed possible typ conversion for lat() / lon() comparison with 0.0f, changed to 0.0 (leaving it to the compiler/optimizer to choose number format)
current log excerpt for NumberFormatException:

- added additional config page (ConfigSearchPage_p) for easy setup of search page layout (to not overload ConfigPortal page)
- currently redundant setting with part of ConfigPortal page
- added missing config for filetype and protocol navigator
- adjusted init of SearchEvent to check navigation config setting
- renamed RankigProcess.getTopicNavigator to getTopics (to distiguish between added SearchEvent.getTopicNavigator)
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.
This attribute can be used for ranking and for other purpose (demand by
customer)
The click depth is computed in two steps:
- during indexing the current fill-state of the reverse link index is
used to backtrack the current page to the root page. The length of that
backtrack is the clickdepth. But this does not discover the shortest
click depth. To get this, a second process to check again is needed
- added a process tag that can be used to do operations on the existing
index after a crawl; i.e. calculation the shortest clickpath. Added a
field to control this operation but not a method to operate on this.
- added a visualization of the clickpath length in the host browser
- urlcitationindex != null check added to ResultEntry.referencesCount
- plus other places where conflicting procedure was used (and urlcitationindex not already checked != null)
that enables viewing of images for intranet SMB servers.
- added a filter search for protocol, tld and ext again; otherwise p2p
search produces a lot of rubbish
- an event type (once, regular) can be selected
- for this event type, a fixed time can be selected. This may be either
directly after startup or at one of the full hours at a day (==25
options)
The main point about this feature is the opportunity to start an action
directly after startup. That makes it possible to create YaCy
distributions which, after started at the first time, start to index
parts of the intranet/internet by itself.

introduce a copy-field for the author field to be copied to a string
field. This field is then used to generate facets. Without this field,
the facet would consist only of the words of the author names, not of
the full author string.
clicks which are necessary to get from the portal of a host to a
specific document. At this time, only the start document is flagged with
clickdepth '0', all other with '-1'. To get the actual clickdepth, a
process must use crawled information to collect the actual number of
clicks. This will be added in another/next step.
INCOMING links to the corresponding web page. This information is taken
from the reverse link index (a 'little sister' of the RWI index).
- this field can be of use to enhance the ranking because a web page
with more incoming links can be more more important than others. But
this is not true for typical link pages like menues. Therefore the
number of outgoing links is needed.
- added a new solr attribute 'bf' to solr queries which is a boost
function extension. this field can contain a formula which comuptes the
boost according to given field values. After some experiments the
following forumla is now default:
div(add(1,references_i),pow(add(1,inboundlinkscount_i),1.6))^0.4
This takes the number of references and the inbound links. Further
experiments are needed to enhance that forumula.
