Both Japanese and romanized titles are ok.
UPC searches may be fuzzy (eg. “UCCD” returns several results), but JAN code searches are exact.
Default behavior is to search for releases which involve the company in any capacity. This scope may be reduced.
Only one input needs to be filled if searching for releases from only one day. Otherwise, fill both boxes to search for releases during that range. Partial dates are ok.
Format searches are fuzzy: eg. “CD” will include CD-R results, and “single” will include maxi-single results.
Credits and notes
This searches both the user-supplied notes and the booklet's liner notes for mention of the provided string. (Romanized liner notes aren't typically available, so it's advised to search for Japanese text only.)
