You should be able to mine the logs for the query, as:
webapp=/solr path=/select params={q=manu:samsung} hits=1 status=0 QTime=3Admittedly you have to do some reconstruction, but it's there. From there, you should be able to run the query against a warmed Solr (but not one that has had that particular query run before). My guess is you're hitting the first time something is done, like sorting or some such occasionally on these queries by chance when a new searcher is opened.
