JSONPath $..book[0,1] fails - Parse error at 1:9 near token , (,)

[Tset-Noitamotua]

How to reproduce

Use JSON data (bookstore.json) and RF test case (bookstore.robot) from issue #7 but replace test case with this one:

Get the first two books
    Get Value From Json    ${bookstore_data}    $..book[0,1]

Result

Parse error at 1:9 near token , (,)

... working alternative with slice

Get the first two books
    # Get Value From Json    ${bookstore_data}    $..book[0,1]  > fails, see above
    Get Value From Json    ${bookstore_data}    $..book[:2]       # wokrs
