I hope there was no trouble on the users's side caused by the replacement of the web server done the day before yesterday. Because of enhanced capacity of the server machine and modification of aLeaves scripts, searches are now processed much faster, say, by hundreds times.
As a result of this change, after a search job is submitted to aLeaves, you will see the page saying 'Search started !' after a bit longer moment than before and will be directly taken to the search result page.
I hope this change will help you a lot.
