There are no other spirits with he Search power, except free spirits and Watchers. The fist category is not available, so only Watchers remain. I think someone did write better Watcher rules to use with Search, but even if not, three watchers is always better than one, especially if you allow one trick. Since the Watchers can rely information in form of mental images, I can help them by using my own Assensing to assist. Plus, they assist each other in the task, so teamwork bonuses apply.
