Search a cell array of structs

I have a large one-dimensional cell array of structs. All the structs have the same format (i.e. same fields in the same order). I would like to search for a particular value in a struct field. E.g. say one of the fields is 'name'. I would like to be able to search the cell array and get back indices of all cells which contain a struct where the 'name' field contains 'sally'. Is there a straight-forward way to do this?

Try
cac{1} = struct( 'name', 'val1' );
cac{2} = struct( 'name', 'val2' );
cac{3} = struct( 'name', 'val3' );
cac{4} = struct( 'name', 'sally' );
strcmp( cellfun( @(sas) sas.name, cac, 'uni', false ), {'sally'} )
which returns
ans =
0 0 0 1
Straight-forward - maybe not.

Yes, 'uni' is a valid shortening of 'UniformOutput'
@(sas) sas.name is the definition of a anonymous function and sas is just an argument.
