Index search doesn't find qFuzzyCompare in QGlobal

If you enter "qFuzzyCompare" in the index search of the assistant you get one hit.
If you open it "qFuzzyCompare(const QTransform & t1, ...)" will be shown.
On another PC it was "qFuzzyCompare(const QQuaternion & q1, ...)".

The expected result would be to get a dialog where you can choose which class, matching the keyword, should be shown. And it should contain <QtGlobal>.
