Search Database Android

I have a database that keeps notes. I want to be able to search this database using a searchview:

SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.search));

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
            @Override
            public boolean onQueryTextSubmit(String query) {

                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {


                What code do I put here

                return true;
            }
        });

What code do I use to search a database

Is this an option? - Cursor cur = DatabaseNote.db.rawQuery()
