Remarks

The SearchWin property was added to provide easy access to the SearchWinTop, SearchWinLeft,
SearchWinWidth and SearchWinHeight Properties from the SPEL

Language. The SearchWin property

allows the setting of all 4 Properties with just 1 function call. There are cases where the user may want to
define the position and size of the Search Window dynamically and for that reason the SearchWin property
was created.

Do not the set the SearchWin setting too large. If the value is too large, the detection time gets longer and
may result in false detection.
