Subject: client_start_search only takes client argument again
X-Git-Tag: mobile-beta-1~3^2
X-Git-Url: http://git.indexdata.com/?a=commitdiff_plain;h=fb486d4fa4ebc56c76bbc8f25c819b1bb4a144f7;p=pazpar2-moved-to-github.git

client_start_search only takes client argument again

So that we re-issue it when host has been resolved.
