I am struggling to form the regex expression from the below String Array `notes`.

I have tried to use few things below but I am not getting what I am expecting, like from `notes[0]` I am only expecting `10.0` and `higher`, Whereas it is printing all the String till the end `higher than in-store`, I though `\b...\b` will pick up the exact match but its not working here.

Any Pointers on this please.

```auto
    notes = ["10.0% higher than in-store", 
             "5.0% lower than in-store", 
             "Same as in-store"]

    String[][] twoDarray= new String[notes.length][2];

    for (int index=0; index<notes.length;index++){ 
        twoDarray[index]= notes[index].split("(\\%) | /\bhigher\b/ | /\blower\b/ | /\bsame\b/ | /\bas\b/");
    }

    System.out.println( twoDarray [0][0]); //10.0 (correct)
    System.out.println( twoDarray [0][1]); //higher than in-store (expected: higher)
    System.out.println( twoDarray [1][0]); //5.0 (correct)
    System.out.println( twoDarray [1][1]); //lower than in-store (expected: lower)
    System.out.println( twoDarray [2][0]); //Same as in-store (expected: Same)
    System.out.println( twoDarray [2][1]); // no output? (expected: as)

```
