Search both channel fields and related entries fields

Question

Let's say I have two channels, call them "primary" and "secondary". Channel secondary is referenced in channel primary as a relationship.

Now I want to search the entries of secondary based on fields from both channels.

So for example:

{exp:channel:entries channel="secondary" search:field1="foo" search:field2="foo" {related_entries}search:field1="foo"{/related_entries}}
// show entries from channel secondary with "foo" in field1 and field2, and field1 from channel primary
{/exp:channel:entries}

Obviously that's just pseudo code, but hopefully it illustrates my aim. Also note that I'm using EE 2.5.2, hence the old style tag pair.

I think I read that I would instead need to use reverse related entries, but I'm not sure how that would work. It seems like that would pose the same problem.

Any help would be appreciated.
