Filter data from two content types with different criteria in view

Question

I've got these two content types, A and B. It's pretty straightforward to set up and display them in the same view. However, I can't get them filtered. I've added two filters rules, one for each content types, a1 and b1 respectively, in the hope that I can extract the right parts of the data from A and B and show them in my view. But that doesn't work out.

// a1=published and content type A and category=aa b1=published and content type B and tag=bb //

Here is what I got while trying to do so:

1. no rules at all, view displays all the stuff from A and B
2. rule a1, view displays A only
3. rule b1, view displays B only
4. rule a1 or b1, shows nothing

   filter groups i used

Is there anything wrong or filter criteria can only be applied? Any help is appreciated.

--update 1-- I did some more experiments about grouping filter criteria:

 - case 1
Content: Published (Yes)  AND  
Content: Type (= Portfolio)  
OR  
Content: Published (Yes)  AND  
Content: Type (= Blog entry)  AND  
Content: Tags (= frontpage) | Settings   
 - case 2
Content: Published (Yes)  AND  
Content: Type (= Portfolio)  
Content: Tags (= frontpage) | Settings   
OR  
Content: Published (Yes)  AND  
Content: Type (= Blog entry)  AND  

"Content: Tags" is a unique field which only appears in content type "Blog entry" . To my surprise, case 1 and 2 will yield the same result, blog entries, even though "Content: Tags" has nothing to do with the content type "portfolio".

--update 2-- a bug?
Incorrect filter group OR behavior

Answer 1

a1 and b1 will show nothing, because content type == A AND content type == B is always false for 'A != B'

On filter block, you have a drop down with options. You need to group them into groups connected with OR, so you will have:

published and ( (content type == A and category == aa) or (content type == B and tag == bb ) )

Answer 2

If you want to show parts (you must mean fields) of your two content types just do the following:

1. Add a filter of Content type checking the two content types A & B
2. At the Format/Show section click on content and on that window choose fields.
3. Then go the Fields section and start adding fields that belong to those types.
