I don't think 尋 stands for seek, searching in this case.尋ねる means ask or inquire but is pronounced as "tazuneru" not "hiro"."hiro" for 尋 means "arm span". Japanese fishers often use hiro as unit of line length and depth.So Chihiro means thousand times of arm span depth. Very similar to "abyss", deliberation. [noted -ed]
