Filtering skill and support gem list is incomplete

Scenario: I (mace user) want to check what skills interact with "Fully broken armour".
I open an uncut skill gem.
Search for "broken"
Sunder is not highlighted, despite the skill details saying "consumes fully broken armour..."

Scenario 2: I want to look for supports that might provide benefit to party members (eg font of blood)
I open an uncut support
Search for "Allies"
No results, even tho the font supports say "grants to allies"
