A recent patch introduced changes to collection search functionality when combining search terms/filters for quantity owned (collected/not collected, q<4, q=1, etc.) and set version (e:sos, e:msh, etc.) so that the number set specific printings are displayed.

This has the presumably unintended consequence of greatly degrading quantity searches that include reprints, since you will only ever own 1 copy of a specific printing of a card if you already owned 3+ copies in different printings before collecting the new version.

See an example in my screenshots. I own 4 copies of Thwip!, originally printed in SPM. When I search for common cards I own fewer than 4 copies of in MSH (q<4 r:c e:msh) it includes Thwip! despite the fact that I own 4 copies of the card INCLUDING the MSH version. When I adjust that search to be for cards I own exactly 4 copies of (q=4) Thwip! no longer appears because I technically own 1 copy.

The problem is not exclusive to quantity+set searches. Cards I technically own more than 4 copies of through reprints are EXCLUDED from a simple "q=4" search.

Quantity owned of a specific printing only has deckbuilding relevance when that number is exactly 0, so that is the only exception case that should be reflected in quantity searches. Allowing this background data in when it cannot possibly be relevant to the player is a mistake and has degraded search functionality.
