This search is different from Google - instead of putting in text, you tell it what kind of melody you're looking for (say, fast, 4/4 or 2/4) - and it returns all of the melodies from the databse that fit your description. The database is currently at 262 melodies.
If you don't know (or don't care) about one of the parameters - just leave all the options un-selected. If all the options in a column are unselected, the results will include melodies matching any of the options.
If you select multiple columns, a result has to match each column to appear. And if you select multiple options within one column, the a melody will appear if it matches any of those parameters (and all of the other columns).
