You'd need a mapping of keywords to songs
Keywords can include popular phrases/lyrics from the song, artist name, album name, genre, etc

For example
bad -> bad blood, bad romance, taylor, swift, taylor swift, lady gaga, gaga, etc
something -> something about you, something in the way you move etc

You would also need a mapping of songs to key words
For example
bad blood -> taylor swift, 1989
something in the way you move -> ellie goulding, delirium etc

You could use these two hash tables to get a list of relevant results for a search keyword/phrase

You could also cache a list of recent search queries and results (for auto fill and fast data service), if needed

Categorized search can also be used, eg search by artist, song, album; this could use category specific tables for quick look up

Given that the question asks about search particularly and not auto complete or suggest, we can build an inverted index data-structure which is the building block of search engines.
