Is it possible to search by name in kanji, if not, could it be implimented?

it already is possible.
simply typing in the manga search will bring up a list of releases by scanlation/official groups. for this, only the specific title (specific reading of the name) listed for the release will be shown.
below the releases is the "Search Series" which will work with kanji/etc, showing results of manga titles as a whole.
