Finder for Drupal 7 and updated API references

Hi there, I'm looking for a

Hi there,

I'm looking for a solution to something I want/need and I'm wondering if the Finder module is what I'm looking for.

It's best if I explain with an example about guitarchords. I have 5 nodes that each contain the information about a song. Part of that information is the chords you need to know if you want to play that song on your guitar. For example:

Song 1 - chords A, E
Song 2 - chords C, D, Em, G
Song 3 - chords A, D
Song 4 - chords A, E
Song 5 - chords A

Nou what I want to do is present a list/filter of chords, and a list of songs you can play. The list of songs will initially be empty (0 results), and will be filled when someone select one or more chords they know how to play. So,

- when you select only the A-chord, song 5 will appear in the list of songs.
- when you select the A-chord and E-chord, songs 1, 4 and 5 appear in the list of songs.
- when tou select the A-chord and D-chord, songs 3 and 5 appear in the list of songs

And so on...

Can Finder module do this?
If not, do you know of a solution that does?

Thanks in advance for taking the time answering.
