CAML Query for Week and Month not working

问题

I following CAML Query does not work:

<Where><DateRangesOverlap><FieldRef Name=\"EventDate\" /><FieldRef Name=\"RecurrenceID\" /><Value Type=\"DateTime\"><Week /></Value></DateRangesOverlap></Where>

AND

<Where><DateRangesOverlap><FieldRef Name=\"EventDate\" /><FieldRef Name=\"RecurrenceID\" /><Value Type=\"DateTime\"><Month/></Value></DateRangesOverlap></Where>

But this one works:

<Where><DateRangesOverlap><FieldRef Name=\"EventDate\" /><FieldRef Name=\"RecurrenceID\" /><Value Type=\"DateTime\"><Yearly /></Value></DateRangesOverlap></Where>

The only difference is that the working query has <Yearly /> as Date time and the non working queries have <Week /> and <Month />.

This is a big issue for me as it has a big performance impact. Can someone provide some guidance as to what muight be happening here?
