In the Toadstoolz Items collection, I was searching for the 'Iron Axe'.
Filtering on keywords such as 'Iron Axe', 'Iron', 'I', 'Axe' did not display any 'Iron Axe' NFTs in the result.
For wood axes, keywords such as 'Wood', 'W', 'oo', 'Axe', etc did display 'Wood Axe' in the result
The results are the same with various letter cases
Keyword filtering also does not work for 'Redwood'
Empty keyword filtering + Trait of 'Tool' does show iron axes
in graphiQL, the name is returning null for some items, perhaps some of which are Iron Axes and other items that can't be filtered right now
