Where are all the stencils that have shapes that are found through search

Hi, I'm using Visio 2010 Standard.

When I click on More Shapes to find additional stencils, I see a fixed list

When when I search for a shape, I find one which is not on any of those stencils. So where are all those additional stencils that have these shapes.

For example, when I searched for 'bar chart' shape I get shapes like 'Bar graph 1'.

But where is the stencil that has all of these shapes?

Thanks
