使用javascript的谷歌搜索的高级搜索功能，但遇到了一些问题

Question

下面是我尝试获取查询字符串值的表单代码。

<form id="form1">
<label for="allthesewords"> all these words</label>
<input type="text" id="allthesewords">
<br>
<label for="thisexactwordphrase">this exact word phrase</label>
<input type="text" id="thisexactwordphrase">
<br>
<label for="anyofthese">any of these</label>
<input type="text" id="anyofthese">
<br>
<label for="noneofthese">none of these</label>
<input type="text" id="noneofthese">
<br>
<input type="submit" value="Advance Search" onClick="advanceSearch()">
</form>

这个是我正在构建查询字符串的 javascript 函数。

function advanceSearch(){
document.getElementById("form1").action="https://www.google.com/search?as_q="+document.getElementById("allthesewords").value+"&as_epq="+document.getElementById("thisexactwordphrase").value+"&as_oq="+document.getElementById("anyofthese").value+"&as_eq="+document.getElementById("noneofthese").value;
return true;
}

因此，实际问题是在单击提交按钮时，它必须重定向到此URL https://www.google.com/search?as_q=Harvard%20univeristy%20students&as_epq=students%20of%20Harvard%20Univeristy&as_oq=Harvard&as_eq=almamater 但是，当我运行代码时，它只是重定向到此 url： https://www.google.com/webhp。

提前谢谢!!!!
