yes, you can copy the users search directly from there saved search to your own, or another users saved searches. I do this all the time when users leave. Once in savedsearches.conf, Copy the search everything after the [NameOfSearch] all the way to the the start of the next [name]. you can put the search in another users savedsearches.conf or in the /etc/apps/search/local/savedsearches.conf if you want to share it with all users.

$splunk_home/etc/users/apps (there may be several apps here but there should at least be "search) inside the appropriate app where user would have created search goto /local and read teh savedsearches.conf.
