[Perlfect-search] Result click opens new window

[Interport Trading]

Question:
How can I make clicking on a result always open in a new window 
rather than the same window?

Issue:
I have set $CONTEXT_SIZE = -1 
If you search for just stop words, it properly does not show any 
results.  However, if you search for regular words plus stop words 
the stop words will also get their own context description line in the 
search result.  Is this supposed to happen?  If so, can I stop it?

Thanks very much for your help!!!
