The SearchWinTop property is set automatically when the user drags the upper horizontal window handle

of a specific object's Search Window or moves an object's Search Window vertically. However, the Top

position of an object's Search Window can also be moved by simply entering a new value in the

SearchWinTop property.

There are cases where the user may want to position the Search Window dynamically and for that reason

the SearchWinTop property can also be set from the SPEL+ Language.
