Ebay Search Question (Slightly Off Topic)

[Collect Equity]

I am trying to do a single ebay search of a long list of specific vintage cards by year, but I can't get it to work and am wondering if someone can help me.

Here is an example (note: I am changing the cards I am searching in this example).

Let's say I wanted to see all the 1952 Mantles and 1968 Ryans. If I enter the searches '1952 Mantle' and '1968 Nolan Ryan' alone, both come up with a bunch of results. But when I try to combine them into " (1952 Mantle, 1968 Nolan Ryan) then it doesn't return the correct results.

Any ideas on why this happens and how I can search a list of 10 different cards by year/player in a single search, instead of doing 10 different searches?

Thanks!
