Re: Multicore and snapshooter / snappuller
Yeah I think the snapshot techniques that ZFS provides would be very
nice for handling indexes, although remains to be seen as I have not
seen too much info pertaining to it.
Im hoping to have a chance to put Solr on OpenSolaris soon and will
see what works / what doesn't. (BTW this combo can be tried out for
free w/ VirtualBox and OpenSolaris .iso if anyone is interested).

sporadic warnings / errors when using a DataImportHandler based solr instance
Hi all, I have a system using DataImportHandler, and it is performing great, but we're getting a couple of sporadic warnings / errors that I'd like to be able to address. The version of solr we are using is a nightly snapshot from 2008-08-02. 1) INFO: PERFORMANCE WARNING: Overlapping onDeckSearchers=2 I doubt this is DataImportMapper related, but it might be related to how we do updates / commits. Can anyone describe the situation that makes this performance warning happen? 2) SEVERE: org.apache.solr.common.SolrException: Error opening new searcher. exceeded limit of maxWarmingSearchers=4, try again later. My instinct says that this one is related to the first one but i'm not sure. 3) WARNING: Could not getStatistics on info bean org.apache.solr.search.SolrIndexSearcher org.apache.lucene.store.AlreadyClosedException: this IndexReader is closed Does this indicate there is a race condition between the info beans and the closing of searchers? enjoy, -jeremy -- Jeremy Hinegardner [EMAIL PROTECTED]

Re: Solr Logo thought
I don't think Hoss wants to be involved in the logo contest beyond the guidance he gave ;) What is there now is really a template I stole from other logo contests. It hasn't really been blessed or finished. For instance, the contest end date should be decided upon. No committer has even really endorsed running the contest - not a big deal, but I think it means things are not yet official. Agreeing that the current rules are fine and deciding on an end date would seem to remedy that. As far as getting other interest beyond the developers, once the contest is blessed, I'd be happy to try and spread the word. I don't predict it will do much good though. However, I think we already have some quality logos and this is really just a chance for late comers to get into the game - so I am personally not so worried about getting other designers (I would like for it to happen though). If people see clear concrete steps ahead that I can help with, just let me know. - Mark Otis Gospodnetic wrote: Hoss, I like the LogoContest page, but I have a feeling it will not result in more logo candidates getting submitted because the only people who know about it are solr-user/dev subscribers, and people here are typically not designers.

SpellCheckComponent bug?
Hello folks! I seem to be seeing a bug in the SpellCheckComponent.. Search term: Quicksilver... I get two suggestions... lst name=suggestion int name=frequency2/int str name=wordQuicksilver/str /lst lst name=suggestion int name=frequency220/int str name=wordQuiksilver/str /lst ...and it's not correctly spelled... bool name=correctlySpelledfalse/bool ...but the collation is of the first term - not the one with the highest frequency? str name=collationQuicksilver/str This seems to be anti-what-the-docs-say collation should do. Other, more popular terms (shoez, runnning, etc) all seem to collate properly. I'm hitting Solr via SolrJ and not really doing anything too fancy - using SVN head at the moment. Just wondered if anyone had any ideas. There are no synonyms in this system, so I don't think that could be it. I've rebuilt the search index. Thanks for your time!

Hi Walter,
As at nightly build of August 19th, the DIH failing to connect to the data

for what is worth,i only have 1 copy of the jdbc jar (MS SQL in my case), in

it's picked up by SOLR's classpath in the Java Info page under admin/
