You simply do this kind of question as a lost object horary. The house in which you find the significator of the object (most likely represented by the 2nd house significator) will show you where the object is, including possible directions and terrain. Usually. There are lots and lots of examples of this type of chart here on the site.

Lost Something in Back Garden

Pam,

I will assume the lost object might be a ring or something of value. When you set up the Horary note the considerations first.

The chart must tell you something about the person asking the question to be considered to be radical.

The Moon is extremely important as it denotes what the querent is thinking about. So note the placement of the Moon. What are the considerations if any?

If the item is of a personal nature to the querent then the 2nd House will indicate where it might be. But without a chart I cant say anymore.
