I noticed again the problem, now I was able to collect some data. in my paste http://pastebin.com/nVwf327c you can see the result of the same query issued twice, the 2nd and 3rd group are swapped.
I pasted also the clusterstate and the core state for each core. The logs did'n show any problem related to indexing, only some malformed query. After doing an optimize the problem disappeared. So, is the problem related to documents that where deleted from the index? The optimization took 5 minutes to complete 2014-10-21 11:41 GMT+02:00 Giovanni Bricconi <giovanni.bricc...@banzai.it>: > Nice! > I will monitor the index and try this if the problem comes back. > Actually the problem was due to small differences in score, so I think the > problem has the same origin > > 2014-10-21 8:10 GMT+02:00 lboutros <boutr...@gmail.com>: > >> Hi Giovanni, >> >> we had this problem as well. >> The cause was that the different nodes have slightly different idf values. >> >> We solved this problem by doing an optimize operation which really remove >> suppressed data. >> >> Ludovic. >> >> >> >> ----- >> Jouve >> France. >> -- >> View this message in context: >> http://lucene.472066.n3.nabble.com/unstable-results-on-refresh-tp4164913p4165086.html >> Sent from the Solr - User mailing list archive at Nabble.com. >> > >
