Here is a view of the process for the search engine Maybe this will explain a little more. I guess I should have said every row in column C..
1. Column A = ARTIST
2. Column B = SONG
3. Column C = FILTER #1 - appears as a search filter (i.e. genre).
4. Column D = FILTER #2 - appears as a search filter (i.e. decade).
5. Column E = DISC # - appears in the final request list as a song location reference (i.e. disc #).
6. Column F = TRACK # - appears in the final request list as a song location reference (i.e. track #).
For FILTER #1 and FILTER #2, the search filters, It is recommended to not have more than 20-30 variations for each field. For example, if you are going to have genre as one of the fields, it is not recommended that you have more than 20-30 different genre types. Having more than this could cause the search page to load very slowly. 30 character max. Other examples of filters can be decade, year, tempo, BPM, style, event, function, mood, date, charts, ranking, etc.
