: -Should I be warming the new searcher with a search which uninverts all of : my fields?
yes. : -If so, will the warming happen before the new searcher is registered? they will if you do them as part of a "newSearcher" event in your solrconfig.xml -- the example solrocnfig.xml has some examples using QuerySenderListener to do this. : -Will searches coming in to the index before the new searcher is registered : but after its created go to the old searcher? yes. : -Will my memory usage spike during this interval? it probably already is -- but yes, the warming of hte new Searcher will require it to use a lot of ram to pre-populate these caches & data structures, in addition to hte caches and data structures being used by the "old" searcher still serving queries. -Hoss
