Let me preface this with... I have referenced this question/answers and it seems to contain clues, but i'm still missing the whole picture
Run JQuery in the context of another frame
Essentially, the structure of the index page is this
<html>
<body>
<div class="frames-wrap">
<iframe id="this-iframe" src="location.php">
</iframe>
</div>
</body>
</html>
location.php then contains a frameset (ahem, not my idea...) that has two frames that are set up like so...
<frameset cols="350,*">
<frame src="search.php" id="frame_search" name="search"/>
<frame src="edit.php" id="frame_edit" name="edit" />
</frameset>
if i want to manipulate objects between the index page and these elements how would i go about this?
I keep thinking the context should be something similar to window.parent.frames[0].document... what else am i missing?

Definition and Usage. The contentDocument property returns the Document object generated by a frame or iframe element. This property can be used in the host window to access the Document object that belongs to a frame or iframe element.
Apart from accessing an element by adding its control to the Controls Repository, there is also the possibility to access an element within a web page's iframe via Javascript.
# jQuery Code to Get HTML Content of IFrame contents(). find("html"). html()); }); The above code will return all the HTML content of our Iframe.
Preface: You wont be able to access the iframes contents unless it originates from the same domain.
To select elements in your iframe you could use a jQuery call like this
element = $("#this_iframe").contents().find("#frame_search")
The key is to use the contents() function. See Traversing/contents

I think the link from technicolorenvy has the answer, but the selector has a lesser known second parameter where you can set the context.
Something like this:
var iframeDoc = document.getElementById('myIframe');
iframeDoc = (iframeDoc.contentWindow) ? iframeDoc.contentWindow : (iframeDoc.contentDocument.document) ? iframeDoc.contentDocument.document : iframeDoc.contentDocument;
// From the parent window
$('p', iframeDoc).html('Hello from parent');

Giving your frames ids that are valid JavaScript identifiers would help, then you could use constructs such as window.top.this_iframe.frame_edit.document as your context.
