- all non-dht targets (previously separated into 'robinson' for dht-like
queries and 'node' for solr queries) are non 'extra' peers, which are
queries using solr
- these extra-peers are now selected using a ranking on last-seen,
peer-tag-matches, node-peer flags, peer age, and link count. The ranking
is done using a weight and a random factor.
- the number of extra peers is 50% of the dht peers
- the dht peers now exclude too young peers to prevent bad results
during strong growth of the network
- the number of dht peers (and therefore extra-peers) is reduced when
the memory of the peer is low and/or some documents still appear in the
indexing-queue. This shall prevent a peer from deadlocks when p2p
queries are made in a fast sequence on weak hardware.
yacy will load linked web pages from search results until the total
number of web pages reaches 15000. This shall give fresh peers a 'boost'
to get faster a personalized search index.
- removed unused solr access classes
- made snippet generation for documents aus YaCy RWI/DHT concurrent (as
it was before the search process removation)
- reduced the number of remote results in settings file because the
processing of such mass documents add is too CPU-intensive (in Solr)
This has two aspects: the user who searches may want to increase these values to get more results and more load on the remote side and the user of the server which is accessed for this search may want to restrict the load. Both sides can now be configured. The server-site maximum load parameters are defined by a network definition and the client-side search request load can be defined by each user individually but when the remote search is done the requested service is limited to the network definition.
You can find now in the network definition file:
network.unit.remotesearch.maxcount and network.unit.remotesearch.maxtime
and in the yacy.conf file:
remotesearch.maxcount and remotesearch.maxtime
There is currently no web interface to define the client-side remote search attributes, please set them manually

Please see new coments in yacy.network.freeworld.unit for details of the new DHT selection methods.
The number of maximum peers is now not fixed to a specific number but may increase with
- the partition exponent
- the number of redundant peers
- the robinson burst percentage
- the multiword burst percentage
The maximum can then be the number of senior peers (all visible peers).

- words are now not deleted from the search index automatically if index receive is switched off
- a flag in the network definition defines if this feature is switched on at all
- the search filter for not-found word references is switched off for server-side remote searches

- 300 ppm is default now (but this is switched off by default; if you switch it on you may want more traffic?)
- better timing for busy queue
- better amount of remote url retrieval
- better time-out values
- better tracking of availability of remote crawl urls
- more logging for result of receipt sending

in the network configuration, you can configure a whiteliste and a blacklist
- blacklistet clients cannot search
- whitelistet client get never any search restrictions
- for all other clients: apply DoS search restrictions
Please see the example configuriation in yacy.network.freeworld.unit
by default, all clients from localhosts get whitlistet.
If you have your own YaCy network, please put all the IPs of your peers into the whitelist

the purpose of this list is not only to view attempts from read attacks, but also to show if the
yacy-yacy protocol is working with respect to the bug that was fixed with SVN 4869
