JavaScript - Como realizar consultas en IndexedDB

database = indexedDB.open("DB", 1);

    database.onupgradeneeded = function (e){

        var active = database.result ;

        var store1 = active.createObjectStore("Questions", {keyPath : 'id', autoincrement : true});

        var store = active.createObjectStore("Replyes", {keyPath : 'id', autoincrement : true});

    };

    var trans = active.transaction (["Questions"], "readwrite");

    var store = trans.objectStore ("Questions");

    var question = document.getElementById("question").getElementsByTagName("td");

    var reply = document.getElementById("reply").getElementsByTagName("td");

    for (i=0; i<question.length; i++){

        var requestQuestion = store.put({ id : i , Question: question[i].innerHTML, Reply: reply[i].innerHTML});

    };

En SQL seria algo tipo;

SELECT * FROM  Questions WHERE id = x;
