This time it works like this: - each peer provides its ranking information using the yacy/idx.json servlet - peers with more than 1 GB ram will load this information from all other peers, combine that into one ranking table and store it locally. This happens during the start-up of the peer concurrently. The new generated file with the ranking information is at DATA/INDEX/<network>/QUEUES/hostIndex.blob - this index is then computed to generate a new fresh ranking table. Peers which can calculate their own ranking table will do that every start-up to get latest feature updates until the feature is stable - I computed new ranking tables as part of the distribition and commit it here also - the YBR feature must be enabled manually by setting the YBR value in the ranking servlet to level 15. A default configuration for that is also in the commit but it does not affect your current installation only fresh peers - a recursive block rank refinement is implemented but disabled at this point. it needs more testing Please play around with the ranking settings and see if this helped to make search results better. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@7729 6c8d7289-2bf4-0310-a012-ef5d649a1542
