Indeed, search is not implemented. It's on the roadmap for the resolver overhaul, which is the next task and should be done sometime next month. One matter that could use discussion is how search should be performed. The queries could be done in parallel, or in series once the previous one fails. In any case the operation cannot complete until there is an initial subsequence of the search list beginning with zero or more negative results followed by a positive result; a positive result with unanswered queries before it is non-conclusive. Also a question is how search should interact with hosts file. If a non-initial search suffix succeeds in the hosts file, should DNS queries still be performed to check if the earlier search suffixes are found via DNS? These kinds of questions are why it's not implemented yet, and they need to be discussed now I think if we're going to get it implemented soon. Rich
