Unexpected results searching on 2 Tags

[mikecox39 13]

 

I wanted to find all the titles in my notebook that had both tag1 and tag2.

I selected 2 tags and imagined my results would be a list of titles with both those tags. In the example that would have been 4 titles.  But in one case only 1 title came up with both tags, in the other 4 tiles; the result I expected, came up plus a dozen others. 

How should I have set this search up, so only the titles that the 2 tags would appear in the result?

"All" should be valid; the second search is "Any" search  

Are you using the child search option?

To wit: in Tools / Options / Navigation : is "Automatically select child tags" checked?
