Do A Search From Popup

I want to do a search from my opened popup and print the result to
my parent window.

I know how can I with a link open a new page in the parent window
but I need to retrieve my form values before to send it to the parent window

I call a function from my search button :

function Lvl_P2P(url,closeIt,delay){
document.select_wish.submit();
opener.location.href = url;
}

my button :
<input type="button"
onClick="Lvl_P2P('/cgi-bin/recordz.cgi?lang=fr&page=dosearchimmo',true,0500)"
value="Search">

but If I use it this way the document.select_wish.submit() method send
and open page in the current pop up window

how can I tell to open it to opener.location.href = url...
