It depends on where you call it. If you are calling it like so:

for(all moves blah blah)
{
...
    if(depth>FULLPLY)
        val=search(...);
    else
        val=qsearch(...);
...
}

then the latter would work. But if you are using it the TSCP way:

if(depth<=0)
    return qsearch(...);
....
for(all moves)
{
    val=search(...);
}

then the former.
