Count of windows in Safari returns one more than actual

Question

First of all I'm completely new to Applescript.
What I do at the moment is to search for scripts that might do something similar to want I want and then modify them to suit my particular requirements.
I have been trying to use a script that searches for a particular URL in Safari.
Here is an excerpt from the script:-
tell application "System Events"
     tell application "Safari"
          set windowCount to count of windows
          repeat ...
     end tell
end tell
The problem is that the value returned by "set windowCount to count of windows" returns a value which is one more than the actual number of Windows that are open.
Can anyone tell me why it is going wrong?
Many Thanks
I'm using Script Editor 2.7(176), AppleScript 2.4 on a late 2008 MacBook running Yosemite 10.10.2 and Safari Version 8.0.3 (10600.3.18)

Hi,
Try this (don't use this script in the 'tell application "System Events"' block) :
set tUrls to {}
tell application "Safari"
    repeat with thisWind in (get windows whose its document is not missing value)
        repeat with thisTab in (get tabs of thisWind)
            set t to URL of thisTab
            if t contains "search string" then set end of tUrls to t
        end repeat
    end repeat
end tell
tUrls
