Songs searching / Lyric display

I've made a website and bundled hundreds of songs into an aplayer.
Now the new problem appears ---> searching songs and lyrics display.
The switch API was written, but it still needs more information to achieve searching function, at least song indexes.
And so on, lyric size is not big enough for some users.

1. Is it possible to develop searching function?

2. The lyric size can be adjusted? or RWD kind to adapt different resolutions?

Thank a lot~!
