Search by chemistry misses some

When I do a search by chemistry for all IMA approved minerals containing Tl, I'm surprised that it does not find Galkhaite, with the formula
(Cs,Tl)(Hg,Cu,Zn)6(As,Sb)4S12
Is there good some reason for that, or is it a bug?

Probably because it's only looking for "essential" elements, not substituting elements?

It's because the search uses the IMA formula, (Hg5Cu)CsAs4S12.
