I'm not sure when this was changed, I think it was either 3.1 or 3.15. Since then, when searching on the market board, if you search for "Adamantite", it lists all gear with Adamantite in its name first, and only after that there's Adamantite Ore, Nuggets and Ingots.

Before this change, those materials would always appear at the top of the search, now we have to wait for the whole item list to load and then scroll down to the bottom.

It would be nice to have the old sorting back (materials appear above finished items) or have it as a config option.
