Paste found text in new frame

Question

I have this script to find my desired text:
var myDoc = app.activeDocument;
// Creates  service Text Frame
myDoc.textFrames.add({
    geometricBounds: [50,-300,740,-70], fillColor: "C=100 M=0 Y=0 K=0", fillTint: 20, name: "Summary"
//Find  text
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = "(.+\\r)(\\+.+$)";
found = app.activeDocument.findGrep ();
alert (found.length)
var new_grep = new Array()
for(a=0; a<found.length; a++)
new_grep[a] = found[a].contents
Now, what I'd like to know is how to paste the found text (the contents of new_grep) into my textFrame "Summary".
Additionally, I should erase substring #2 (\\+.+$) from the original frame...
Trying and trying but I can't find my way, I know, it should be damn simple...
Thanks,
Guido

Hi Jongware,
after a bit I returned to my script and, of course... it doesn't work anymore!
This is what I'm up to:
var myDoc = app.activeDocument;
// Creates  service Text Frame
myDoc.textFrames.add({
    geometricBounds: [50,-300,740,-70], fillColor: "C=100 M=0 Y=0 K=0", fillTint: 20, name: "Summary"
//Find text
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = "(.+\\r)(\\r\\+.+$ \\r)";
myFind = app.activeDocument.findGrep ();
var myCount=0;
for (i=0; i<myFind.length; i++)
alert (myFind)
myDoc.textFrames.item ("Summary").contents=myDoc.textFrames.item ("Summary").contents+myFind[i].contents+"\r";
myCount++;
// Delete "+ foto"
app.findGrepPreferences = null;
app.findGrepPreferences.findWhat = "(\\r\\+ FOTO.+$)";
myDoc.selection[0].changeGrep();
The new frame is created, but nothing gets pasted in it.
I DO REMEMBER it used to work (that was before my hard disk crashed and I had to open my iMac to replace it...), God knows what I've done wrong.
Suggestions?
Thx,
