how can I get quality results looking for comic books?

I'm working on an application to track completed sales for comic books. The problem is, I'm not getting much for accurate results. For example, if I use "findCompletedItems" and include the keywords "Hulk (2014) #1", I get results for "Thanos vs. Hulk (2014) #1B VF/NM 9.0", "Hulk (2014) #16 NM (1:25 Yu Variant)", "SHE-HULK # 1", etc. After doing a bit more digging, I found I should look for the product, then do a search by the productID. I do have UPC #s for the majority of my comics, so this is an extremely practical idea. The problem is, UPCs work for movies and music, but not comics. Comics might have ISBN #s, but nothing I can easily get my hands on. So is there a better way I should go about this? I'm hoping for an automated solution that I won't have to hand curate, but it seems like I might be hitting a wall. I'm hoping someone can help point me in the right direction.

EAN and UPC may map to ISBNs in some cases, but magazine publishers don't all use UPC and older comics pre-date UPC codes. You should also be aware that comic UPC numbers are reused and are not unique to specific editions. The UPCs on these are identical: http://www.ebay.com/itm/Incredible-Hulk-227-Fine-1962-Marvel-Comics-CBX2-/301587882737 http://www.ebay.com/itm/HULK-1962-Series-323-/281841416870 See here too: https://forums.developer.ebay.com/questions/13801/finditemsbyproduct-using-ean-codes-always-fails-bu.html

I do see that I'm limited in my results, but so far, this is comfortably the best that it looks like I'll be able to get. I've tried searching by the ISBN with the UPC, and I'm still coming up with no results. I checked the link too and tried "findItemsAdvanced" using the upc as the keyword, still no luck. Comics seem to be living in their own world between books and collectibles. It's too bad there isn't a more detailed search where I can narrow things down to get a 1 to 1 match for a product to its product id, even if users aren't doing that with their listings, I'd atleast know when I'm doing a search that the results I do return are accurate.
